Looks fine to me. Feel free to commit it!
One question this brings up, though: According to wikipedia, there is
also a 64-bit variant; would that use a different u-boot?
All the u-boot packages are marked "multi-arch: same", but if there's
the possibility of both an armhf and amd64 u-boot-tegra package
containing different builds, maybe we'll need to reconsider how to
handle multi-arch with u-boot packaging...

You could perhaps include a TODO item in the README (or a separate TODO
file); that might stir someone else to submit improved docs...
