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.

	  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 && OF
	help

	select MMC_SDHCI_IO_ACCESSORS
	help
	  This selects the Freescale eSDHC controller support on the platform
	  bus, found on platforms like mx35/51.

	  If unsure, say N.

config MMC_SDHCI_DOVE
	bool "SDHCI support on Marvell's Dove SoC"

	help
	  This selects the Secure Digital Host Controller Interface (SDHCI)
	  often referrered to as the HSMMC block in some of the Samsung S3C
	  range of SoC.

	  Note, due to the problems with DMA, the DMA support is only
	  available with CONFIG_EXPERIMENTAL is selected.

	  If you have a controller with this interface, say Y or M here.

	  If unsure, say N.

config MMC_SDHCI_PXA
	tristate "Marvell PXA168/PXA910/MMP2 SD Host Controller support"

config MMC_SDHCI_S3C_DMA
	bool "DMA support on S3C SDHCI"
	depends on MMC_SDHCI_S3C && EXPERIMENTAL
	help
	  Enable DMA support on the Samsung S3C SDHCI glue. The DMA
	  has proved to be problematic if the controller encounters
	  certain errors, and thus should be treated with care.

	  YMMV.

endchoice

config MMC_ATMELMCI_DMA
	bool "Atmel MCI DMA support (EXPERIMENTAL)"
	depends on MMC_ATMELMCI && (AVR32 || ARCH_AT91SAM9G45) && DMA_ENGINE && EXPERIMENTAL
	help
	  Say Y here to have the Atmel MCI driver use a DMA engine to
	  do data transfers and thus increase the throughput and
	  reduce the CPU utilization. Note that this is highly
	  experimental and may cause the driver to lock up.

	  If unsure, say N.

config MMC_IMX
	tristate "Motorola i.MX Multimedia Card Interface support"
	depends on ARCH_MX1
	help
	  This selects the Motorola i.MX Multimedia card Interface.

	help
	  Say Y here if you want to be able to access MMC/SD cards with
	  the Texas Instruments(R) Flash Media card reader, found in many
	  laptops.
	  This option 'selects' (turns on, enables) 'TIFM_CORE', but you
	  probably also need appropriate card reader host adapter, such as
	  'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
	  (TIFM_7XX1)'.

          To compile this driver as a module, choose M here: the
	  module will be called tifm_sd.

config MMC_MVSDIO

	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

	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

	help
	  This option enables support for MMC/SD part of ENE CB710/720 Flash
	  memory card reader found in some laptops (ie. some versions of
	  HP Compaq nx9500).

	  This driver can also be built as a module. If so, the module
	  will be called cb710-mmc.

	depends on PCI
	help
