a08458303e atmel_mci: Fix data timeout value
Calculate the data timeout based on values from the CSD instead of
just using a hardcoded DTOR value. This is a backport of a similar fix
in BSP 2.0, with one additional fix: the DTOCYC value is rounded up
instead of down.

f0d1246ed7 atmel_mci: Use 512 byte blocksize if possible
Instead of always using the largest blocksize the card supports, check
if it can support smaller block sizes and use 512 bytes if possible.
Most cards do support this, and other parts of u-boot seem to have
trouble with block sizes different from 512 bytes.

Also enable underrun/overrun protection.

fc26c97bb6 Atmel MCI driver
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
