Regular U-boot recently added this patch, http://git.denx.de/?p=u-boot.git;a=commitdiff;h=8003c361deec3ee651451662efd05352f1abdd40 and while browsing the U-boot v2 tree (the layout looks very nice indeed!), I saw that it was leaving the stack unaligned. This caused me a lot of problems in regular U-boot and quite a bit of headache, so it would be nice to have it fixed in v2 as well. This is completely untested, and if I misunderstood something about the code so that the stack is aligned elsewhere, please ignore the patch.
