Since this doesn't change the at91/boot2 stuff at all, the stuff I
care most about will still work.

I'd like to merge these two files, since I didn't see anything in the
diffs that can't be resolved between the two systems...  I wouldn't
block commits based on this, but these two files are very similar...
