Seems the voltage bit defenitions in sdmmcreg.h for voltages below 2V
are not quite right. At least I can't find them in any of the MMC and
SD card documentation I can find on the interwebs. Instead there is a
single "low voltage bit" that indicates support for the 1.65-1.95V or
1.70-1.95V range depending on the document you're reading. Go with the
1.65-1.95V range as that is what Linux does.
Necessary (but not sufficient) to make the eMMC on the ASUS X205TA work.
ok jsg@ (who did the armv7 bits)
