8 tristate "ARM AMBA Multimedia Card Interface support"

22 If you have a PXA(R) platform with a Multimedia Card slot,
28 tristate "Secure Digital Host Controller Interface support"
31 This selects the generic Secure Digital Host Controller Interface.
32 It is used by manufacturers such as Texas Instruments(R), Ricoh(R)
33 and Toshiba(R). Most controllers found in laptops are of this type.
35 If you have a controller with this interface, say Y or M here. You
36 also need to enable an appropriate bus interface.
40 config MMC_SDHCI_IO_ACCESSORS
44 This is silent Kconfig symbol that is selected by the drivers that
45 need to overwrite SDHCI IO memory accessors.
47 config MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
49 select MMC_SDHCI_IO_ACCESSORS
51 This option is selected by drivers running on big endian hosts
52 and performing I/O to a SDHCI controller through a bus that
53 implements a hardware byte swapper using a 32-bit datum.
54 This endian mapping mode is called "data invariance" and
55 has the effect of scrambling the addresses and formats of data
56 accessed in sizes other than the datum size.
58 This is the case for the Freescale eSDHC and Nintendo Wii SDHCI.
