This one really should be at least 3 separate patches:
* s/tegra_init_early/tegra20_init_early/ in machine descriptions
* Switch reset mechanism from CAR to PMC
* tegra_init_cache modifications
* Not sure if all the ifdef additions go in the above, or if some should be
  separate?

Still, I think it's probably OK to go in as it is even if it isn't optimal.
