[U-Boot] [PATCH v4 02/13] tegra20: move tegra20 SoC code to arch/arm/cpu/tegra20-common

Allen Martin
2012-06-22T00:00:36Z

In preparation for splitting out the armv4t code from tegra20, move
the tegra20 SoC code to arch/arm/cpu/tegra20-common. This code will
be compiled armv4t for the arm7tdmi and armv7 for the cortex A9.
