  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.

  76           proprietary controller is unnecessary because the SDHCI driver
  77           supports MMC cards on the SD controller, but if it is not
  78           disabled, it will steal the MMC cards away - rendering them
  79           useless. It is safe to select this even if you don't
