Common Tegra files are in arch-tegra, shared between T20 and T30. Tegra30-specific headers are in arch-tegra30. Note that some of these will be filled in as more T30 support is added (drivers, WB/LP0 support, etc.). A couple of Tegra20 files were changed to support common headers in arch-tegra, also.
