4 bool "Ethernet support"
5 depends on ETRAX_ARCH_V32 && NETDEVICES
8 This option enables the ETRAX FS built-in 10/100Mbit Ethernet
12 bool "PHY not present"
13 depends on ETRAX_ETHERNET
15 This option disables all MDIO communication with an ethernet
16 transceiver connected to the MII interface. This option shall
17 typically be enabled if the MII interface is connected to a
18 switch. This option should normally be disabled. If enabled,
19 speed and duplex will be locked to 100 Mbit and full duplex.
22 bool "Serial-port support"

44 bool "Serial port 0 enabled"
45 depends on ETRAXFS_SERIAL
47 Enables the ETRAX FS serial driver for ser0 (ttyS0)

87 Selecting this option will make it run in DMA mode.
89 config ETRAX_SYNCHRONOUS_SERIAL_PORT1
90 bool "Synchronous serial port 1 enabled"
91 depends on ETRAX_SYNCHRONOUS_SERIAL && ETRAXFS
93 Enabled synchronous serial port 1.

96 bool "Enable DMA on synchronous serial port 1."
97 depends on ETRAX_SYNCHRONOUS_SERIAL_PORT1

100 Selecting this option will make it run in DMA mode.
102 config ETRAX_AXISFLASHMAP
103 bool "Axis flash-map support"
104 depends on ETRAX_ARCH_V32
107 select MTD_CFI_AMDSTD
108 select MTD_JEDECPROBE
110 select MTD_COMPLEX_MAPPINGS
113 This option enables MTD mapping of flash devices. Needed to use
114 flash memories. If unsure, say Y.
116 config ETRAX_AXISFLASHMAP_MTD0WHOLE
117 bool "MTD0 is whole boot flash device"
118 depends on ETRAX_AXISFLASHMAP
120 When this option is not set, mtd0 refers to the first partition
121 on the boot flash device. When set, mtd0 refers to the whole
122 device, with mtd1 referring to the first partition etc.
124 config ETRAX_PTABLE_SECTOR
125 int "Byte-offset of partition table sector"
126 depends on ETRAX_AXISFLASHMAP
129 Byte-offset of the partition table in the first flash chip.
130 The default value is 64kB and should not be changed unless
131 you know exactly what you are doing. The only valid reason
132 for changing this is when the flash block size is bigger
133 than 64kB (e.g. when using two parallel 16 bit flashes).
135 config ETRAX_NANDFLASH
136 bool "NAND flash support"
137 depends on ETRAX_ARCH_V32
140 This option enables MTD mapping of NAND flash devices. Needed to use
141 NAND flash memories. If unsure, say Y.
143 config ETRAX_NANDBOOT
144 bool "Boot from NAND flash"
145 depends on ETRAX_NANDFLASH
147 This options enables booting from NAND flash devices.
148 Say Y if your boot code, kernel and root file system is in

175 for cryptographic operations.
178 tristate "MMC/SD host driver using IO-processor"
179 depends on ETRAX_ARCH_V32 && MMC
181 This option enables the SD/MMC host controller interface.
182 The host controller is implemented using the built in
183 IO-Processor. Only the SPU is used in this implementation.
186 # Make this one of several "choices" (possible simultaneously but
187 # suggested uniquely) when an IOP driver emerges for "real" MMC/SD
190 depends on !ETRAX_MMC_IOP
195 # While the board info is MMC_SPI only, the drivers are written to be
196 # independent of MMC_SPI, so we'll keep SPI non-dependent on the
197 # MMC_SPI config choices (well, except for a single depends-on-line
198 # for the board-info file until a separate non-MMC SPI board file
200 # FIXME: When that happens, we'll need to be able to ask for and
201 # configure non-MMC SPI ports together with MMC_SPI ports (if multiple
202 # SPI ports are enabled).

230 Say Y for an MMC/SD socket connected to synchronous serial port 0,
