I don't even know whether my e-mail went through to the conference. I just
wanted to know, if not being able to use SD card on this board using a
vanilla modern U-Boot SPL is a known bug, or if there are any people
outthere using it successfully. Probably not, or they are not interested in
sharing the simple fact.

With rc3 I'm getting exactly the same errors:
