I see. I have not tried any of the MMC u-boot stuff for my board (a 
sam9m10g45ek).

I stopped working on improving the December release because it was clear that a lot of good things were happening to the MMC framework and the underlying AT91 framework was in flux so it seemed like a good idea to wait until that stabilized before I revisit putting a modern U-Boot on my boards "the right way".
Ahh, Wolfgang compatible :). I still haven't really figured out exactly what is
actually correct with the AT91 framework code yet. I just started playing with
this a few weeks ago. There was a patch a little which back which was the
reference implementation for the AT91 framework, but I could not find it when I
searched my mail box.

Ah, so dual RAM is no matter for you.

Which config header are you using? Naturally, I am using the sam9m10g45ek
header, but since you have a slightly different board, which doesn't
appear to have a header, how did you proceed?

Best regards,
Alex
