  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
