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.

Signed-off-by: Tom Warren twarren@nvidia.com --- V2: * Created common header files in arch-tegra. * Reworked pmux func name enums, RSVDx values to end of list. * Added spl.h for T30, removed emc.h. V3: * Use 408MHz for PLLP.

This provides SPL support for T30 boards - AVP early init, plus CPU (A9) init/jump to main U-Boot.

Some changes were made to Tegra20 cpu.c to move common routines into tegra-common/cpu.c and reduce code duplication.

Signed-off-by: Tom Warren twarren@nvidia.com --- V2: * Move common CPU init code to tegra-common/cpu.c V3: * Use 408MHz for PLLP. * Cleanup whitespace
