[U-Boot] [PATCH v2 6/7] Tegra30: Add generic Tegra30 build support

Tom Warren
2012-12-03T23:45:21Z

This patch adds basic Tegra30 (T30) build support - no specific
board is targeted.

Signed-off-by: Tom Warren <twarren@nvidia.com>
---
V2:
* Use generic CONFIG_TEGRA in Makefile instead of specific SOC test
* Cleanup a couple of include files due to T20/T30 build differences
* Move pinmux_init to board code
