  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
