 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.

 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
