I have not tried booting u-boot proper from mainline. It just seemed pointless to me to be working from 2 source trees to make a single product. I will give it a go though. As Chin Liang See has said, there are two issues thwarting this: legal AND source conformance. The code we can fix, the legal can only be fixed by bending Altera - I am going to do that too.
