[U-Boot] [PATCH] AVR32: switch to generic mmc framework

[Sven Schnelle]

Hi List,

these patches switch all AVR32 boards to the generic MMC framework. Motivation
for doing so is to be able to boot from SDHC cards. The second patch removes
the legacy atmel_mci driver, as it is no longer used by any board.

I've only tried this code on the Atmel ATNGW100, as i have no other AVR32 boards.
Would be great if some other users could try that patch on different platforms.

It seems like the gen_atmel_mci driver doesn't work with Multible Block transfer on
AVR32, but the old code didn't used that mode either. So that's something for the TODO
list for future improvements.

Regards,

Sven
