41	help
42	  This selects the generic Secure Digital Host Controller Interface.

60	depends on MMC_SDHCI
61	select MMC_SDHCI_IO_ACCESSORS
62	help
63	  This option is selected by drivers running on big endian hosts
64	  and performing I/O to a SDHCI controller through a bus that
65	  implements a hardware byte swapper using a 32-bit datum.
66	  This endian mapping mode is called "data invariance" and
67	  has the effect of scrambling the addresses and formats of data
68	  accessed in sizes other than the datum size.

88	  This adds a pci quirk to disable Ricoh MMC Controller. This
89	  proprietary controller is unnecessary because the SDHCI driver
90	  supports MMC cards on the SD controller, but if it is not
91	  disabled, it will steal the MMC cards away - rendering them
92	  useless. It is safe to select this even if you don't
93	  have a Ricoh based card reader.
