If I'm not mistaken, the current u-boot-tegra/master branch has issues
with ./MAKEALL arm, not building everything it should. I'd rather not
pull it unless Allen's fix is added (or even better, unless the master
branch is force-updated to fix the original commit which introduced the
issue, if you and Allen are willing to go this far).
