  75           This endian mapping mode is called "data invariance" and
  76           has the effect of scrambling the addresses and formats of data
  77           accessed in sizes other than the datum size.

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