  63           proprietary controller is unnecessary because the SDHCI driver
  64           supports MMC cards on the SD controller, but if it is not
  65           disabled, it will steal the MMC cards away - rendering them
  66           useless. It is safe to select this driver even if you don't
  67           have a Ricoh based card reader.
