Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs.
The AT91 ARM-based CPUs use basically the same hardware, so it should
be possible to share this driver, but no effort has been made so far.
Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from
