# # MMC/SD host controller drivers # comment "MMC/SD/SDIO Host Controller Drivers" config MMC_ARMMMCI tristate "ARM AMBA Multimedia Card Interface support" depends on ARM_AMBA help This selects the ARM(R) AMBA(R) PrimeCell Multimedia Card Interface (PL180 and PL181) support. If you have an ARM(R) platform with a Multimedia Card slot, say Y or M here. If unsure, say N. config MMC_PXA tristate "Intel PXA25x/26x/27x Multimedia Card Interface support" depends on ARCH_PXA help This selects the Intel(R) PXA(R) Multimedia card Interface. If you have a PXA(R) platform with a Multimedia Card slot, say Y or M here. If unsure, say N. config MMC_SDHCI tristate "Secure Digital Host Controller Interface support" depends on HAS_DMA help This selects the generic Secure Digital Host Controller Interface. It is used by manufacturers such as Texas Instruments(R), Ricoh(R) and Toshiba(R). Most controllers found in laptops are of this type. If you have a controller with this interface, say Y or M here. You also need to enable an appropriate bus interface. If unsure, say N. config MMC_SDHCI_IO_ACCESSORS bool depends on MMC_SDHCI help This is silent Kconfig symbol that is selected by the drivers that need to overwrite SDHCI IO memory accessors. config MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER bool select MMC_SDHCI_IO_ACCESSORS help This option is selected by drivers running on big endian hosts and performing I/O to a SDHCI controller through a bus that implements a hardware byte swapper using a 32-bit datum. This endian mapping mode is called "data invariance" and has the effect of scrambling the addresses and formats of data accessed in sizes other than the datum size. This is the case for the Freescale eSDHC and Nintendo Wii SDHCI. config MMC_SDHCI_PCI tristate "SDHCI support on PCI bus" depends on MMC_SDHCI && PCI help This selects the PCI Secure Digital Host Controller Interface. Most controllers found today are PCI devices. If you have a controller with this interface, say Y or M here. If unsure, say N. config MMC_RICOH_MMC bool "Ricoh MMC Controller Disabler (EXPERIMENTAL)" depends on MMC_SDHCI_PCI help This adds a pci quirk to disable Ricoh MMC Controller. This proprietary controller is unnecessary because the SDHCI driver supports MMC cards on the SD controller, but if it is not disabled, it will steal the MMC cards away - rendering them useless. It is safe to select this even if you don't have a Ricoh based card reader. If unsure, say Y. config MMC_SDHCI_OF tristate "SDHCI support on OpenFirmware platforms" depends on MMC_SDHCI && PPC_OF help This selects the OF support for Secure Digital Host Controller Interfaces.

If unsure, say N. config MMC_SPI tristate "MMC/SD/SDIO over SPI" depends on SPI_MASTER && !HIGHMEM && HAS_DMA select CRC7 select CRC_ITU_T help Some systems access MMC/SD/SDIO cards using a SPI controller instead of using a "native" MMC/SD/SDIO controller. This has a disadvantage of being relatively high overhead, but a compensating advantage of working on many systems without dedicated MMC/SD/SDIO controllers. If unsure, or if your system has no SPI master driver, say N. config MMC_S3C tristate "Samsung S3C SD/MMC Card Interface support" depends on ARCH_S3C2410 help This selects a driver for the MCI interface found in Samsung's S3C2410, S3C2412, S3C2440, S3C2442 CPUs. If you have a board based on one of those and a MMC/SD slot, say Y or M here. If unsure, say N. config MMC_S3C_HW_SDIO_IRQ bool "Hardware support for SDIO IRQ" depends on MMC_S3C help Enable the hardware support for SDIO interrupts instead of using the generic polling code. choice prompt "Samsung S3C SD/MMC transfer code" depends on MMC_S3C config MMC_S3C_PIO bool "Use PIO transfers only" help Use PIO to transfer data between memory and the hardware. PIO is slower than DMA as it requires CPU instructions to move the data. This has been the traditional default for the S3C MCI driver. config MMC_S3C_DMA bool "Use DMA transfers only (EXPERIMENTAL)" depends on EXPERIMENTAL help Use DMA to transfer data between memory and the hardare. Currently, the DMA support in this driver seems to not be working properly and needs to be debugged before this option is useful. config MMC_S3C_PIODMA bool "Support for both PIO and DMA (EXPERIMENTAL)" help Compile both the PIO and DMA transfer routines into the driver and let the platform select at run-time which one is best. See notes for the DMA option. endchoice config MMC_SDRICOH_CS tristate "MMC/SD driver for Ricoh Bay1Controllers (EXPERIMENTAL)" depends on EXPERIMENTAL && PCI && PCMCIA help Say Y here if your Notebook reports a Ricoh Bay1Controller PCMCIA card whenever you insert a MMC or SD card into the card slot.
