It is not just this board. It is any board using an old mainline
u-boot. Any such system will not boot with a kernel after 3.1. It was
at that point that the issue was found and fixed in u-boot. My Bubba3
has a u-boot before that point...

I'm away for the weekend, so cannot test it.

It would be good to at least put the fix into the impedance matcher,
so there is no need to mess with the kernel.
