If you are willing to ship u-boot with known and nasty to debug
problem, it is your choice.

Either the patch is good or it is bad, my future plans should have
nothing to do with it. Notice that this patch does not help _me_ in
any way, as I know about the issue and am unlikely to hit it again,
and that original problem still breaks the build on my system.

Help from someone knowing ARM assembly would be nice. Now that we know
what the problem is, it should not be too bad.

Best regards,
