[U-Boot] AT91SAM9xxx SDCard/MMC support?

[Reinhard Meyer (-VC)]

Hello,

apparently none of the mainstream u-boot designs use
SDCard/MMC.

It appears that this task should not be a huge problem,
the MCI for both AVR32 and AT91SAM9 seems to be identical
(and MCI on AVR32 works).

But before I perhaps reinvent anything already done, I
prefer to ask here. Also any input what obstacles have
been found would be appreciated.

I need the support for 9260/9G20/9XE.

Best Regards
Reinhard
