They are all broken beyond repair. Given that nobody has complained
about them (most haven't worked in 2.6 AT ALL), remove them from the
tree.

A new mitsumi driver that actually works is in progress, it'll get
added when completed.

-         If you have a CD-ROM drive that is neither SCSI nor IDE/ATAPI, say Y

-
-         Note that the answer to this question doesn't directly affect the

-         the questions about these CD-ROM drives. If you are unsure what you
-         have, say Y and find out whether you have one of the following
-         drives.
-
-         For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
-         exists. Especially in cases where you do not know exactly which kind

-         interface parameters and switch some internal goodies.
-
-         To compile these CD-ROM drivers as a module, choose M instead of Y.
-
-         If you want to use any of these CD-ROM drivers, you also have to

-         "electrically compatible" drives (Vertos, Genoa, some Funai models)
-         are currently not supported; for the Sanyo H94A drive currently a
-         separate driver (asked later) is responsible.  Most drives have a
-         uniquely shaped faceplate, with a caddyless motorized drawer, but
-         without external brand markings.  The older CR-52x drives have a

-         driver is able to do an extended auto-probing for interface
-         addresses and drive types; this can help to find facts in cases you

-       HISTORY
-       V0.0    Adaption to Aztech CD268-01A Version 1.3
-               Version is PRE_ALPHA, unresolved points:
-               1. I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW
-                  thus driver causes CPU overhead and is very slow 
-               2. could not find a way to stop the drive, when it is
-                  in data read mode, therefore I had to set
-                  msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one
-                  frame can be read in sequence, this is also the reason for
-               3. getting 'timeout in state 4' messages, but nevertheless
-                  it works
-               W.Zimmermann, Oct. 31, 1994
-       V0.1    Version is ALPHA, problems #2 and #3 resolved.  
-               W.Zimmermann, Nov. 3, 1994
-       V0.2    Modification to some comments, debugging aids for partial test
-               with Borland C under DOS eliminated. Timer interrupt wait 
-               STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented; 
-               use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_
-               SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy 
-               waiting seems better to me than interrupt rescheduling.
-               Besides that, when used in the wrong place, STEN_LOW_WAIT causes
-               kernel panic.
-               In function aztPlay command ACMD_PLAY_AUDIO added, should make
-               audio functions work. The Aztech drive needs different commands
-               to read data tracks and play audio tracks.
-               W.Zimmermann, Nov. 8, 1994
-       V0.3    Recognition of missing drive during boot up improved (speeded up).
-               W.Zimmermann, Nov. 13, 1994
-       V0.35   Rewrote the control mechanism in azt_poll (formerly mcd_poll) 
-               including removal of all 'goto' commands. :-); 
-               J. Nardone, Nov. 14, 1994
-       V0.4    Renamed variables and constants to 'azt' instead of 'mcd'; had
-               to make some "compatibility" defines in azt.h; please note,
-               that the source file was renamed to azt.c, the include file to
-               azt.h                
-               Speeded up drive recognition during init (will be a little bit 
-               slower than before if no drive is installed!); suggested by
-               Robby Schirmer.
-               read_count declared volatile and set to AZT_BUF_SIZ to make
-               drive faster (now 300kB/sec, was 60kB/sec before, measured
-               by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096';
-               different AZT_BUF_SIZes were test, above 16 no further im-
-               provement seems to be possible; suggested by E.Moenkeberg.
-               W.Zimmermann, Nov. 18, 1994
-       V0.42   Included getAztStatus command in GetQChannelInfo() to allow
-               reading Q-channel info on audio disks, if drive is stopped, 
-               and some other bug fixes in the audio stuff, suggested by 
-               Robby Schirmer.
-               Added more ioctls (reading data in mode 1 and mode 2).
-               Completely removed the old azt_poll() routine.
-               Detection of ORCHID CDS-3110 in aztcd_init implemented.
-               Additional debugging aids (see the readme file).
-               W.Zimmermann, Dec. 9, 1994  
-       V0.50   Autodetection of drives implemented.
-               W.Zimmermann, Dec. 12, 1994
-       V0.52   Prepared for including in the standard kernel, renamed most
-               variables to contain 'azt', included autoconf.h
-               W.Zimmermann, Dec. 16, 1994        
-       V0.6    Version for being included in the standard Linux kernel.
-               Renamed source and header file to aztcd.c and aztcd.h
-               W.Zimmermann, Dec. 24, 1994
-       V0.7    Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case
-               CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl,
-               which causes kernel crashes when playing audio, changed 
-               include-files (config.h instead of autoconf.h, removed
-               delay.h)
-               W.Zimmermann, Jan. 8, 1995
-       V0.72   Some more modifications for adaption to the standard kernel.
-               W.Zimmermann, Jan. 16, 1995
-        V0.80   aztcd is now part of the standard kernel since version 1.1.83.
-                Modified the SET_TIMER and CLEAR_TIMER macros to comply with
-                the new timer scheme.
-                W.Zimmermann, Jan. 21, 1995
-        V0.90   Included CDROMVOLCTRL, but with my Aztech drive I can only turn
-                the channels on and off. If it works better with your drive, 
-                please mail me. Also implemented ACMD_CLOSE for CDROMSTART.
-                W.Zimmermann, Jan. 24, 1995
-        V1.00   Implemented close and lock tray commands. Patches supplied by
-               Frank Racis        
-                Added support for loadable MODULEs, so aztcd can now also be
-                loaded by insmod and removed by rmmod during run time
-                Werner Zimmermann, Mar. 24, 95
-        V1.10   Implemented soundcard configuration for Orchid CDS-3110 drives
-                connected to Soundwave32 cards. Release for LST 2.1.
-                (still experimental)
-                Werner Zimmermann, May 8, 95
-        V1.20   Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but
-                sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver-
-                sion needs an update of Dosemu0.60's cdrom.c, which will come with the 
-                next revision of Dosemu.
-                Also Soundwave32 support now works.
-                Werner Zimmermann, May 22, 95
-       V1.30   Auto-eject feature. Inspired by Franc Racis (racis@psu.edu)
-               Werner Zimmermann, July 4, 95
-       V1.40   Started multisession support. Implementation copied from mcdx.c
-               by Heiko Schlittermann. Not tested yet.
-               Werner Zimmermann, July 15, 95
-        V1.50   Implementation of ioctl CDROMRESET, continued multisession, began
-                XA, but still untested. Heavy modifications to drive status de-
-                tection.
-                Werner Zimmermann, July 25, 95
-        V1.60   XA support now should work. Speeded up drive recognition in cases, 
-                where no drive is installed.
-                Werner Zimmermann, August 8, 1995
-        V1.70   Multisession support now is completed, but there is still not 
-                enough testing done. If you can test it, please contact me. For
-                details please read Documentation/cdrom/aztcd
-                Werner Zimmermann, August 19, 1995
-        V1.80   Modification to suit the new kernel boot procedure introduced
-                with kernel 1.3.33. Will definitely not work with older kernels.
-                Programming done by Linus himself.
-                Werner Zimmermann, October 11, 1995
-       V1.90   Support for Conrad TXC drives, thank's to Jochen Kunz and Olaf Kaluza.
-               Werner Zimmermann, October 21, 1995
-        V2.00   Changed #include "blk.h" to <linux/blk.h> as the directory
-                structure was changed. README.aztcd is now /usr/src/docu-
-                mentation/cdrom/aztcd
-                Werner Zimmermann, November 10, 95
-        V2.10   Started to modify azt_poll to prevent reading beyond end of
-                tracks.
-                Werner Zimmermann, December 3, 95
-        V2.20   Changed some comments
-                Werner Zimmermann, April 1, 96
-        V2.30   Implemented support for CyCDROM CR520, CR940, Code for CR520 
-               delivered by H.Berger with preworks by E.Moenkeberg.
-                Werner Zimmermann, April 29, 96
-        V2.40   Reorganized the placement of functions in the source code file
-                to reflect the layered approach; did not actually change code
-                Werner Zimmermann, May 1, 96
-        V2.50   Heiko Eissfeldt suggested to remove some VERIFY_READs in 
-                aztcd_ioctl; check_aztcd_media_change modified 
-                Werner Zimmermann, May 16, 96       
-       V2.60   Implemented Auto-Probing; made changes for kernel's 2.1.xx blocksize
-                Adaption to linux kernel > 2.1.0
-               Werner Zimmermann, Nov 29, 97
-               
-        November 1999 -- Make kernel-parameter implementation work with 2.3.x 
-                        Removed init_module & cleanup_module in favor of 
-                        module_init & module_exit.

-* Sony CDU-31A CDROM interface device driver.
-*
-* Corey Minyard (minyard@wf-rch.cirr.com)
-*
-* Colossians 3:17
-*
-*  See Documentation/cdrom/cdu31a for additional details about this driver.
-* 
-* The Sony interface device driver handles Sony interface CDROM
-* drives and provides a complete block-level interface as well as an
-* ioctl() interface compatible with the Sun (as specified in
-* include/linux/cdrom.h).  With this interface, CDROMs can be
-* accessed and standard audio CDs can be played back normally.
-*
-* WARNING -    All autoprobes have been removed from the driver.
-*              You MUST configure the CDU31A via a LILO config
-*              at boot time or in lilo.conf.  I have the
-*              following in my lilo.conf:
-*
-*                append="cdu31a=0x1f88,0,PAS"
-*
-*              The first number is the I/O base address of the
-*              card.  The second is the interrupt (0 means none).
- *             The third should be "PAS" if on a Pro-Audio
- *             spectrum, or nothing if on something else.
- *
- * This interface is (unfortunately) a polled interface.  This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables.  Some (like mine) do not even have the capability to
- * handle interrupts or DMA.  For this reason you will see a lot of
- * the following:
- *
- *   retry_count = jiffies+ SONY_JIFFIES_TIMEOUT;
- *   while (time_before(jiffies, retry_count) && (! <some condition to wait for))
- *   {
- *      while (handle_sony_cd_attention())
- *         ;
- *
- *      sony_sleep();
- *   }
- *   if (the condition not met)
- *   {
- *      return an error;
- *   }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try.  it also handles attentions, which are
- * asynchronous events from the drive informing the driver that a disk
- * has been inserted, removed, etc.
- *
- * NEWS FLASH - The driver now supports interrupts but they are
- * turned off by default.  Use of interrupts is highly encouraged, it
- * cuts CPU usage down to a reasonable level.  I had DMA in for a while
- * but PC DMA is just too slow.  Better to just insb() it.
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk.  The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal.  A lot of conversion goes on.
- *
- * DRIVER SPECIAL FEATURES
- * -----------------------
- *
- * This section describes features beyond the normal audio and CD-ROM
- * functions of the drive.
- *
- * XA compatibility
- *
- * The driver should support XA disks for both the CDU31A and CDU33A.
- * It does this transparently, the using program doesn't need to set it.
- *
- * Multi-Session
- *
- * A multi-session disk looks just like a normal disk to the user.
- * Just mount one normally, and all the data should be there.
- * A special thanks to Koen for help with this!
- * 
- * Raw sector I/O
- *
- * Using the CDROMREADAUDIO it is possible to read raw audio and data
- * tracks.  Both operations return 2352 bytes per sector.  On the data
- * tracks, the first 12 bytes is not returned by the drive and the value
- * of that data is indeterminate.

- * TODO: 
- *       CDs with form1 and form2 sectors cause problems
- *       with current read-ahead strategy.
- *
- * Credits:
- *    Heiko Eissfeldt <heiko@colossus.escape.de>
- *         For finding abug in the return of the track numbers.
- *         TOC processing redone for proper multisession support.
- *
- *
- *  It probably a little late to be adding a history, but I guess I
- *  will start.
- *
- *  10/24/95 - Added support for disabling the eject button when the
- *             drive is open.  Note that there is a small problem
- *             still here, if the eject button is pushed while the
- *             drive light is flashing, the drive will return a bad
- *             status and be reset.  It recovers, though.
- *
- *  03/07/97 - Fixed a problem with timers.
- *
- *
- *  18 Spetember 1997 -- Ported to Uniform CD-ROM driver by 
- *                 Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- *                 changes by Erik Andersen <andersee@debian.org>
- *
- *  24 January 1998 -- Removed the scd_disc_status() function, which was now
- *                     just dead code left over from the port.
- *                          Erik Andersen <andersee@debian.org>
- *
- *  16 July 1998 -- Drive donated to Erik Andersen by John Kodis
- *                   <kodis@jagunet.com>.  Work begun on fixing driver to
- *                   work under 2.1.X.  Added temporary extra printks
- *                   which seem to slow it down enough to work.
- *
- *  9 November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *                    Removed init_module & cleanup_module in favor of 
- *                    module_init & module_exit.
- *                    Torben Mathiasen <tmm@image.dk>
- *
- * 22 October 2004 -- Make the driver work in 2.6.X
- *                   Added workaround to fix hard lockups on eject
- *                   Fixed door locking problem after mounting empty drive
- *                   Set double-speed drives to double speed by default
- *                   Removed all readahead things - not needed anymore

-History:
- Started 25 jan 1994. Waiting for documentation...
- 22 feb 1995: 0.1a first reasonably safe polling driver.
-             Two major bugs, one in read_sector and one in 
-             do_cm206_request, happened to cancel!
- 25 feb 1995: 0.2a first reasonable interrupt driven version of above.
-              uart writes are still done in polling mode. 
- 25 feb 1995: 0.21a writes also in interrupt mode, still some
-             small bugs to be found... Larger buffer. 
-  2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in
-              initialization), read_ahead of 16. Timeouts implemented.
-             unclear if they do something...
-  7 mrt 1995: 0.23 Start of background read-ahead.
- 18 mrt 1995: 0.24 Working background read-ahead. (still problems)
- 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
-              Statistics implemented, though separate stats206.h.
-             Accessible through ioctl 0x1000 (just a number).
-             Hard to choose between v1.2 development and 1.1.75.
-             Bottom-half doesn't work with 1.2...
-             0.25a: fixed... typo. Still problems...
-  1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n.
-  5 apr 1995: 0.27 Auto-probe for the adapter card base address.
-              Auto-probe for the adaptor card irq line.
-  7 apr 1995: 0.28 Added lilo setup support for base address and irq.
-              Use major number 32 (not in this source), officially
-             assigned to this driver.
-  9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause,
-              resume, eject. Play_track ignores track info, because we can't 
-             read a table-of-contents entry. Toc_entry is implemented
-             as a `placebo' function: always returns start of disc. 
-  3 may 1995: 0.30 Audio support completed. The get_toc_entry function
-              is implemented as a binary search. 
- 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to 
-              satisfy; changed binary search into linear search.
-             Auto-probe for base address somewhat relaxed.
-  1 jun 1995: 0.32 Removed probe_irq_on/off for module version.
- 10 jun 1995: 0.33 Workman still behaves funny, but you should be
-              able to eject and substitute another disc.
-
- An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg
-
- 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering 
-              verify_area's in the ioctls. Some bugs introduced by 
-             EM considering the base port and irq fixed. 
-
- 18 dec 1995: 0.35 Add some code for error checking... no luck...
-
- We jump to reach our goal: version 1.0 in the next stable linux kernel.
-
- 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on
-             request of Thomas Quinot. 
- 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR:
-             open only for ioctl operation, e.g., for operation of
-             tray etc.
- 4 apr 1996:  0.97 First implementation of layer between VFS and cdrom
-              driver, a generic interface. Much of the functionality
-             of cm206_open() and cm206_ioctl() is transferred to a
-             new file cdrom.c and its header ucdrom.h. 
-
-             Upgrade to Linux kernel 1.3.78. 
-
- 11 apr 1996  0.98 Upgrade to Linux kernel 1.3.85
-              More code moved to cdrom.c
-             0.99 Some more small changes to decrease number
-             of oopses at module load; 
- 27 jul 1996  0.100 Many hours of debugging, kernel change from 1.2.13
-             to 2.0.7 seems to have introduced some weird behavior
-             in (interruptible_)sleep_on(&cd->data): the process
-             seems to be woken without any explicit wake_up in my own
-             code. Patch to try 100x in case such untriggered wake_up's 
-             occur. 
-
- 28 jul 1996  0.101 Rewriting of the code that receives the command echo,
-             using a fifo to store echoed bytes. 
-
-             Branch from 0.99:
-             0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t
-             (emoenke) various typos found by others.  extra
-             module-load oops protection.
-             0.99.1.1 Initialization constant cdrom_dops.speed
-             changed from float (2.0) to int (2); Cli()-sti() pair
-             around cm260_reset() in module initialization code.
-             0.99.1.2 Changes literally as proposed by Scott Snyder
-             <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which
-             have to do mainly with the poor minor support i had. The
-             major new concept is to change a cdrom driver's
-             operations struct from the capabilities struct. This
-             reflects the fact that there is one major for a driver,
-             whilst there can be many minors whith completely
-             different capabilities.
-
-             0.99.1.3 More changes for operations/info separation.
-
-             0.99.1.4 Added speed selection (someone had to do this
-             first).
-
-  23 jan 1997 0.99.1.5 MODULE_PARMS call added.
-
-  23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as 
-             0.99.1.1--0.99.1.5. I get too many complaints about the
-             drive making read errors. What't wrong with the 2.0+
-             kernel line? Why get i (and othe cm206 owners) weird
-             results? Why were things good in the good old 1.1--1.2 
-             era? Why don't i throw away the drive?
-
- 2 feb 1997   0.102 Added `volatile' to values in cm206_struct. Seems to 
-             reduce many of the problems. Rewrote polling routines
-             to use fixed delays between polls. 
-             0.103 Changed printk behavior. 
-             0.104 Added a 0.100 -> 0.100.1.1 change
-
-11 feb 1997   0.105 Allow auto_probe during module load, disable
-              with module option "auto_probe=0". Moved some debugging
-             statements to lower priority. Implemented select_speed()
-             function. 
-
-13 feb 1997   1.0 Final version for 2.0 kernel line. 
-
-             All following changes will be for the 2.1 kernel line. 
-
-15 feb 1997   1.1 Keep up with kernel 2.1.26, merge in changes from 
-              cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS. 
-
-14 sep 1997   1.2 Upgrade to Linux 2.1.55.  Added blksize_size[], patch
-              sent by James Bottomley <James.Bottomley@columbiasc.ncr.com>.
-
-21 dec 1997   1.4 Upgrade to Linux 2.1.72.  
-
-24 jan 1998   Removed the cm206_disc_status() function, as it was now dead
-              code.  The Uniform CDROM driver now provides this functionality.
-             
-9 Nov. 1999   Make kernel-parameter implementation work with 2.3.x 
-             Removed init_module & cleanup_module in favor of 
-             module_init & module_exit.

- * Parts of the code are based upon lmscd.c written by Kai Petzke,
- * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin
- * Harriss, but any off-the-shelf dynamic programming algorithm won't
- * be able to find them.
- *
- * The cm206 drive interface and the cm260 adapter card seem to be 
- * sufficiently different from their cm205/cm250 counterparts
- * in order to write a complete new driver.
- * 
- * I call all routines connected to the Linux kernel something
- * with `cm206' in it, as this stuff is too series-dependent.

-/*     Revision history
-
-
-       14-5-95         v0.0    Plays sound tracks. No reading of data CDs yet.
-                               Detection of disk change doesn't work.
-       21-5-95         v0.1    First ALPHA version. CD can be mounted. The
-                               device major nr is borrowed from the Aztech
-                               driver. Speed is around 240 kb/s, as measured
-                               with "time dd if=/dev/cdrom of=/dev/null \
-                               bs=2048 count=4096".
-       24-6-95         v0.2    Reworked the #defines for the command codes
-                               and the like, as well as the structure of
-                               the hardware communication protocol, to
-                               reflect the "official" documentation, kindly
-                               supplied by C.K. Tan, Optics Storage Pte. Ltd.
-                               Also tidied up the state machine somewhat.
-       28-6-95         v0.3    Removed the ISP-16 interface code, as this
-                               should go into its own driver. The driver now
-                               has its own major nr.
-                               Disk change detection now seems to work, too.
-                               This version became part of the standard
-                               kernel as of version 1.3.7
-       24-9-95         v0.4    Re-inserted ISP-16 interface code which I
-                               copied from sjcd.c, with a few changes.
-                               Updated README.optcd. Submitted for
-                               inclusion in 1.3.21
-       29-9-95         v0.4a   Fixed bug that prevented compilation as module
-       25-10-95        v0.5    Started multisession code. Implementation
-                               copied from Werner Zimmermann, who copied it
-                               from Heiko Schlittermann's mcdx.
-       17-1-96         v0.6    Multisession works; some cleanup too.
-       18-4-96         v0.7    Increased some timing constants;
-                               thanks to Luke McFarlane. Also tidied up some
-                               printk behaviour. ISP16 initialization
-                               is now handled by a separate driver.
-                               
-       09-11-99                Make kernel-parameter implementation work with 2.3.x 
-                               Removed init_module & cleanup_module in favor of 
-                               module_init & module_exit.

- *  VERSION HISTORY
- *
- *  0.1  initial release, April/May 93, after mcd.c (Martin Harriss)
- *
- *  0.2  thek "repeat:"-loop in do_sbpcd_request did not check for
- *       end-of-request_queue (resulting in kernel panic).
- *       Flow control seems stable, but throughput is not better.  
- *
- *  0.3  interrupt locking totally eliminated (maybe "inb" and "outb"
- *       are still locking) - 0.2 made keyboard-type-ahead losses.
- *       check_sbpcd_media_change added (to use by isofs/inode.c)
- *       - but it detects almost nothing.
- *
- *  0.4  use MAJOR 25 definitely.
- *       Almost total re-design to support double-speed drives and
- *       "naked" (no sound) interface cards ("LaserMate" interface type).
- *       Flow control should be exact now.
- *       Don't occupy the SbPro IRQ line (not needed either); will
- *       live together with Hannu Savolainen's sndkit now.
- *       Speeded up data transfer to 150 kB/sec, with help from Kai
- *       Makisara, the "provider" of the "mt" tape utility.
- *       Give "SpinUp" command if necessary.
- *       First steps to support up to 4 drives (but currently only one).
- *       Implemented audio capabilities - workman should work, xcdplayer
- *       gives some problems.
- *       This version is still consuming too much CPU time, and
- *       sleeping still has to be worked on.
- *       During "long" implied seeks, it seems possible that a 
- *       ReadStatus command gets ignored. That gives the message
- *       "ResponseStatus timed out" (happens about 6 times here during
- *       a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
- *       handled without data error, but it should get done better.
- *
- *  0.5  Free CPU during waits (again with help from Kai Makisara).
- *       Made it work together with the LILO/kernel setup standard.
- *       Included auto-probing code, as suggested by YGGDRASIL.
- *       Formal redesign to add DDI debugging.
- *       There are still flaws in IOCTL (workman with double speed drive).
- *
- *  1.0  Added support for all drive IDs (0...3, no longer only 0)
- *       and up to 4 drives on one controller.
- *       Added "#define MANY_SESSION" for "old" multi session CDs.
- *
- *  1.1  Do SpinUp for new drives, too.
- *       Revised for clean compile under "old" kernels (0.99pl9).
- *
- *  1.2  Found the "workman with double-speed drive" bug: use the driver's
- *       audio_state, not what the drive is reporting with ReadSubQ.
- *
- *  1.3  Minor cleanups.
- *       Refinements regarding Workman.
- *
- *  1.4  Read XA disks (PhotoCDs) with "old" drives, too (but only the first
- *       session - no chance to fully access a "multi-session" CD).
- *       This currently still is too slow (50 kB/sec) - but possibly
- *       the old drives won't do it faster.
- *       Implemented "door (un)lock" for new drives (still does not work
- *       as wanted - no lock possible after an unlock).
- *       Added some debugging printout for the UPC/EAN code - but my drives 
- *       return only zeroes. Is there no UPC/EAN code written?
- *
- *  1.5  Laborate with UPC/EAN code (not better yet).
- *       Adapt to kernel 1.1.8 change (have to explicitly include
- *       <linux/string.h> now).
- *
- *  1.6  Trying to read audio frames as data. Impossible with the current
- *       drive firmware levels, as it seems. Awaiting any hint. ;-)
- *       Changed "door unlock": repeat it until success.
- *       Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
- *       won't get confused).
- *       Added a third interface type: Sequoia S-1000, as used with the SPEA
- *       Media FX sound card. This interface (usable for Sony and Mitsumi 
- *       drives, too) needs a special configuration setup and behaves like a 
- *       LaserMate type after that. Still experimental - I do not have such
- *       an interface.
- *       Use the "variable BLOCK_SIZE" feature (2048). But it does only work
- *       if you give the mount option "block=2048".
- *       The media_check routine is currently disabled; now that it gets
- *       called as it should I fear it must get synchronized for not to
- *       disturb the normal driver's activity.
- *
- *  2.0  Version number bumped - two reasons:
- *       - reading audio tracks as data works now with CR-562 and CR-563. We
- *       currently do it by an IOCTL (yet has to get standardized), one frame
- *       at a time; that is pretty slow. But it works.
- *       - we are maintaining now up to 4 interfaces (each up to 4 drives):
- *       did it the easy way - a different MAJOR (25, 26, ...) and a different
- *       copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
- *       distinguished by the value of SBPCD_ISSUE and the driver's name),
- *       and a common sbpcd.h file.
- *       Bettered the "ReadCapacity error" problem with old CR-52x drives (the
- *       drives sometimes need a manual "eject/insert" before work): just
- *       reset the drive and do again. Needs lots of resets here and sometimes
- *       that does not cure, so this can't be the solution.
- *
- *  2.1  Found bug with multisession CDs (accessing frame 16).
- *       "read audio" works now with address type CDROM_MSF, too.
- *       Bigger audio frame buffer: allows reading max. 4 frames at time; this
- *       gives a significant speedup, but reading more than one frame at once
- *       gives missing chunks at each single frame boundary.
- *
- *  2.2  Kernel interface cleanups: timers, init, setup, media check.
- *
- *  2.3  Let "door lock" and "eject" live together.
- *       Implemented "close tray" (done automatically during open).
- *
- *  2.4  Use different names for device registering.
- *
- *  2.5  Added "#if EJECT" code (default: enabled) to automatically eject
- *       the tray during last call to "sbpcd_release".
- *       Added "#if JUKEBOX" code (default: disabled) to automatically eject
- *       the tray during call to "sbpcd_open" if no disk is in.
- *       Turn on the CD volume of "compatible" sound cards, too; just define
- *       SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
- *
- *  2.6  Nothing new.  
- *
- *  2.7  Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
- *       0 disables, 1 enables auto-ejecting. Useful to keep the tray in
- *       during shutdown.
- *
- *  2.8  Added first support (still BETA, I need feedback or a drive) for
- *       the Longshine LCS-7260 drives. They appear as double-speed drives
- *       using the "old" command scheme, extended by tray control and door
- *       lock functions.
- *       Found (and fixed preliminary) a flaw with some multisession CDs: we
- *       have to re-direct not only the accesses to frame 16 (the isofs
- *       routines drive it up to max. 100), but also those to the continuation
- *       (repetition) frames (as far as they exist - currently set fix as
- *       16..20).
- *       Changed default of the "JUKEBOX" define. If you use this default,
- *       your tray will eject if you try to mount without a disk in. Next
- *       mount command will insert the tray - so, just fill in a disk. ;-)
- *
- *  2.9  Fulfilled the Longshine LCS-7260 support; with great help and
- *       experiments by Serge Robyns.
- *       First attempts to support the TEAC CD-55A drives; but still not
- *       usable yet.
- *       Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
- *       multi session CDs more "transparent" (redirection handling has to be
- *       done within the isofs routines, and only for the special purpose of
- *       obtaining the "right" volume descriptor; accesses to the raw device
- *       should not get redirected).
- *
- *  3.0  Just a "normal" increment, with some provisions to do it better. ;-)
- *       Introduced "#define READ_AUDIO" to specify the maximum number of 
- *       audio frames to grab with one request. This defines a buffer size
- *       within kernel space; a value of 0 will reserve no such space and
- *       disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
- *       of a whole second with one command, but will use a buffer of more
- *       than 172 kB.
- *       Started CD200 support. Drive detection should work, but nothing
- *       more.
- *
- *  3.1  Working to support the CD200 and the Teac CD-55A drives.
- *       AT-BUS style device numbering no longer used: use SCSI style now.
- *       So, the first "found" device has MINOR 0, regardless of the
- *       jumpered drive ID. This implies modifications to the /dev/sbpcd*
- *       entries for some people, but will help the DAU (german TLA, english:
- *       "newbie", maybe ;-) to install his "first" system from a CD.
- *
- *  3.2  Still testing with CD200 and CD-55A drives.
- *
- *  3.3  Working with CD200 support.
- *
- *  3.4  Auto-probing stops if an address of 0 is seen (to be entered with
- *       the kernel command line).
- *       Made the driver "loadable". If used as a module, "audio copy" is
- *       disabled, and the internal read ahead data buffer has a reduced size
- *       of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
- *
- *  3.5  Provisions to handle weird photoCDs which have an interrupted
- *       "formatting" immediately after the last frames of some files: simply
- *       never "read ahead" with MultiSession CDs. By this, CPU usage may be
- *       increased with those CDs, and there may be a loss in speed.
- *       Re-structured the messaging system.
- *       The "loadable" version no longer has a limited READ_AUDIO buffer
- *       size.
- *       Removed "MANY_SESSION" handling for "old" multi session CDs.
- *       Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
- *       Started again to support the TEAC CD-55A drives, now that I found
- *       the money for "my own" drive. ;-)
- *       The TEAC CD-55A support is fairly working now.
- *       I have measured that the drive "delivers" at 600 kB/sec (even with
- *       bigger requests than the drive's 64 kB buffer can satisfy), but
- *       the "real" rate does not exceed 520 kB/sec at the moment. 
- *       Caused by the various changes to build in TEAC support, the timed
- *       loops are de-optimized at the moment (less throughput with CR-52x
- *       drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
- *
- *  3.6  Fixed TEAC data read problems with SbPro interfaces.
- *       Initial size of the READ_AUDIO buffer is 0. Can get set to any size
- *       during runtime.
- *
- *  3.7  Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
- *       drives) which allow only one drive (ID 0); this avoids repetitive
- *       detection under IDs 1..3. 
- *       Elongated cmd_out_T response waiting; necessary for photo CDs with
- *       a lot of sessions.
- *       Bettered the sbpcd_open() behavior with TEAC drives.
- *
- *  3.8  Elongated max_latency for CR-56x drives.
- *
- *  3.9  Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
- *       configuration bug.
- *       Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
- *       the config_spea() routine into their drivers. ;-)
- *
- *  4.0  No "big step" - normal version increment.
- *       Adapted the benefits from 1.3.33.
- *       Fiddled with CDROMREADAUDIO flaws.
- *       Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
- *       seems not to support it).
- *       Fulfilled "read audio" for CD200 drives, with help of Pete Heist
- *       (heistp@rpi.edu).
- *
- *  4.1  Use loglevel KERN_INFO with printk().
- *       Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
- *       to the Longshine LCS-7260. Give feedback if you can - I never saw
- *       such a drive, and I have no specs.
- *
- *  4.2  Support for Teac 16-bit interface cards. Can't get auto-detected,
- *       so you have to jumper your card to 0x2C0. Still not 100% - come
- *       in contact if you can give qualified feedback.
- *       Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
- *       flood of unwanted messages and the accompanied delay, try to read
- *       my documentation. Especially the Linux CDROM drivers have to do an
- *       important job for the newcomers, so the "distributed" version has
- *       to fit some special needs. Since generations, the flood of messages
- *       is user-configurable (even at runtime), but to get aware of this, one
- *       needs a special mental quality: the ability to read.
- *       
- *  4.3  CD200F does not like to receive a command while the drive is
- *       reading the ToC; still trying to solve it.
- *       Removed some redundant verify_area calls (yes, Heiko Eissfeldt
- *       is visiting all the Linux CDROM drivers ;-).
- *       
- *  4.4  Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
- *       experiments: "KLOGD_PAUSE".
- *       Inhibited "play audio" attempts with data CDs. Provisions for a
- *       "data-safe" handling of "mixed" (data plus audio) Cds.
- *
- *  4.5  Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
- *       special end_request routine: we seem to have to take care for not
- *       to have two processes working at the request list. My understanding
- *       was and is that ll_rw_blk should not call do_sbpcd_request as long
- *       as there is still one call active (the first call will care for all
- *       outstanding I/Os, and if a second call happens, that is a bug in
- *       ll_rw_blk.c).
- *       "Check media change" without touching any drive.
- *
- *  4.6  Use a semaphore to synchronize multi-activity; elaborated by Rob
- *       Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
- *       against "ioctl" and vice versa. This could be refined further, but
- *       I guess with almost no performance increase.
- *       Experiments to speed up the CD-55A; again with help of Rob Riggs
- *       (to be true, he gave both, idea & code. ;-)
- *
- *  4.61 Ported to Uniform CD-ROM driver by 
- *       Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- *       changes by Erik Andersen <andersee@debian.org>
- *
- *  4.62 Fix a bug where playing audio left the drive in an unusable state.
- *         Heiko Eissfeldt <heiko@colossus.escape.de>
- *
- *  November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *                  Removed init_module & cleanup_module in favor of 
- *                  module_init & module_exit.
- *                  Torben Mathiasen <tmm@image.dk>
- *
- *  4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
- *             Annoying things fixed:
- *             TOC reread on automated disk changes
- *             TOC reread on manual cd changes
- *             Play IOCTL tries to play CD before it's actually ready... sometimes.
- *             CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.
- *             Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000
- *
- *  4.64 Fix module parameters - were being completely ignored.
- *      Can also specify max_drives=N as a setup int to get rid of
- *      "ghost" drives on crap hardware (aren't they all?)   Paul Gortmaker
- *
- *  TODO
- *     implement "read all subchannel data" (96 bytes per frame)
- *     remove alot of the virtual status bits and deal with hardware status
- *     move the change of cd for audio to a better place
- *     add debug levels to insmod parameters (trivial)
- *
- *     special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
- *     elaborated speed-up experiments (and the fabulous results!), for

- *  should modify INIT_REQUEST and end_request instead, and
- *  change every block device..
- *
- *  Could be a race here?? Could e.g. a timer interrupt schedule() us?
- *  If so, we should copy end_request here, and do it right.. (or
- *  modify end_request and the block devices).
- *
- *  In any case, the race here would be much small than it was, and

- * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
- * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
- * specify the REAL address here, not the configuration port address. Look
- * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
- * sbpcd auto-probe, if you are not firm with the address.
- * There are some soundcards on the market with 0x0630, 0x0650, ...; their
- * type is not obvious (both types are possible).
- *
- * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
- *          if your soundcard has its CDROM port above 0x300, specify
- *          that address and try SBPRO 0 first.
- *          if your SoundScape configuration port is at 0x330, specify
- *          0x338 and SBPRO 2.
- *
- * interface type:
- * ===============
- * set SBPRO to 1 for "true" SoundBlaster card
- * set SBPRO to 0 for "compatible" soundcards and
- *                for "poor" (no sound) interface cards.
- * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
- * set SBPRO to 3 for Teac 16bit interface cards
- *
- * Almost all "compatible" sound boards need to set SBPRO to 0.
- * If SBPRO is set wrong, the drives will get found - but any
- * data access will give errors (audio access will work).
- * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
- * interface cards need SBPRO 1.
- *
- * sound base:
- * ===========
- * The SOUND_BASE definition tells if we should try to turn the CD sound
- * channels on. It will only be of use regarding soundcards with a SbPro
- * compatible mixer.
- *
- * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
- *          #define SOUND_BASE 0     leaves the soundcard untouched

- *  This driver is based on pre-works by Eberhard Moenkeberg (emoenke@gwdg.de);
- *  it was developed under use of mcd.c from Martin Harriss, with help of
- *  Eric van der Maarel (H.T.M.v.d.Maarel@marin.nl).
- *
- *  It is planned to include these routines into sbpcd.c later - to make
- *  a "mixed use" on one cable possible for all kinds of drives which use
- *  the SoundBlaster/Panasonic style CDROM interface. But today, the
- *  ability to install directly from CDROM is more important than flexibility.

- *  History:
- *  1.1 First public release with kernel version 1.3.7.
- *      Written by Vadim Model.
- *  1.2 Added detection and configuration of cdrom interface
- *      on ISP16 soundcard.
- *      Allow for command line options: sjcd=<io_base>,<irq>,<dma>
- *  1.3 Some minor changes to README.sjcd.
- *  1.4 MSS Sound support!! Listen to a CD through the speakers.
- *  1.5 Module support and bugfixes.
- *      Tray locking.
- *  1.6 Removed ISP16 code from this driver.
- *      Allow only to set io base address on command line: sjcd=<io_base>
- *      Changes to Documentation/cdrom/sjcd
- *      Added cleanup after any error in the initialisation.
- *  1.7 Added code to set the sector size tables to prevent the bug present in 
- *      the previous version of this driver.  Coded added by Anthony Barbachan 
- *      from bugfix tip originally suggested by Alan Cox.
- *
- *  November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *                  Removed init_module & cleanup_module in favor of 
- *                  module_init & module_exit.

- * Sony CDU-535 interface device driver
- *
- * This is a modified version of the CDU-31A device driver (see below).
- * Changes were made using documentation for the CDU-531 (which Sony
- * assures me is very similar to the 535) and partial disassembly of the
- * DOS driver.  I used Minyard's driver and replaced the CDU-31A
- * commands with the CDU-531 commands.  This was complicated by a different
- * interface protocol with the drive.  The driver is still polled.
- *
- * Data transfer rate is about 110 Kb/sec, theoretical maximum is 150 Kb/sec.
- * I tried polling without the sony_sleep during the data transfers but
- * it did not speed things up any.
- *
- * 1993-05-23 (rgj) changed the major number to 21 to get rid of conflict
- * with CDU-31A driver.  This is the also the number from the Linux
- * Device Driver Registry for the Sony Drive.  Hope nobody else is using it.
- *
- * 1993-08-29 (rgj) remove the configuring of the interface board address
- * from the top level configuration, you have to modify it in this file.
- *
- * 1995-01-26 Made module-capable (Joel Katz <Stimpson@Panix.COM>)
- *
- * 1995-05-20
- *  Modified to support CDU-510/515 series
- *      (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *  Fixed to report verify_area() failures
- *      (Heiko Eissfeldt <heiko@colossus.escape.de>)
- *

- *  More changes to support CDU-510/515 series
- *      (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x 
- *                 Removed init_module & cleanup_module in favor of 
- *                 module_init & module_exit.
- *                  Torben Mathiasen <tmm@image.dk>
- *

- * Sony CDROM interface device driver.
- *
- * Corey Minyard (minyard@wf-rch.cirr.com) (CDU-535 complaints to Ken above)
- *
- * Colossians 3:17
- *
- * The Sony interface device driver handles Sony interface CDROM
- * drives and provides a complete block-level interface as well as an
- * ioctl() interface compatible with the Sun (as specified in
- * include/linux/cdrom.h).  With this interface, CDROMs can be
- * accessed and standard audio CDs can be played back normally.
- *
- * This interface is (unfortunately) a polled interface.  This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables.  Some (like mine) do not even have the capability to
- * handle interrupts or DMA.  For this reason you will see a bit of
- * the following:
- *
- *   snap = jiffies;
- *   while (jiffies-snap < SONY_JIFFIES_TIMEOUT)
- *   {
- *             if (some_condition())
- *         break;
- *      sony_sleep();
- *   }
- *   if (some_condition not met)
- *   {
- *      return an_error;
- *   }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try.  (The conditional is written so that jiffies
- * wrap-around is handled properly.)
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk.  The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal.  A lot of conversion goes on.
