Since you're reving the patch, a blank line between the two machines would
be nice.

That variable doesn't exist until the next patch; that'll break git bisect.

Do the two DT_MACHINE_START's need if be ifdef'd based on CONFIG variables too?
If not, I'm not sure how a Tegra20- or Tegra30-only kernel builds, since aren't
some of those init functions ifdef'd out but referenced here?
