8aaa15e202 The OCR register defines both acceptable voltage bits, as well as bits 
for other things.  Mask out the voltage only bits when returning the
Vdd mask for voltage computation.

14eced725c A careful reading of the disclaimer that is required to download the 
SD Simplified specification, as well as other SD and SDIO
implemenations I've examined, suggest this disclaimer may be required.
It is unclear to me exactly what the license would be for, or why it
might be required.  Err on the side of caution and include this
disclaimer so anybody deploying this code can judge for themselves.  I
have no further unformation about the details.

114b4164dd Preliminary MMC stack. This stack supports SD 1.0 cards only, but 
should be easily adapted to SD 2.0 (aka SDHC), SDIO, MMC and MMCplus
cards.  At the present time, there's only one bridge driver for the
ARM9 based Atmel AT91RM9200.
