 43           It is used by manufacturers such as Texas Instruments(R), Ricoh(R)
 44           and Toshiba(R). Most controllers found in laptops are of this type.

 64           implements a hardware byte swapper using a 32-bit datum.
 65           This endian mapping mode is called "data invariance" and
 66           has the effect of scrambling the addresses and formats of data
 67           accessed in sizes other than the datum size.

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