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

  77           supports MMC cards on the SD controller, but if it is not
  78           disabled, it will steal the MMC cards away - rendering them
