Sorry for the late reply, I am horribly overloaded now. I asked someone
in #u-boot who has the DE0-NANO-SOC board to test latest u-boot/master
on it and it apparently worked for him. I should get some more feedback
in the morning [ see http://pastebin.com/CM1QJGnh ] .

Still, this is getting real creepy. You are the second person who is
complaining about misbehavior of terasic boards with mainline u-boot
and whatever I do, I cannot replicate this.

I am at least CCing the Altera guys. Sorry I have no better suggestion
for you :(

Best regards,
