[U-Boot] [PATCH 1/9] tegra2: move tegra2 SoC code to arch/arm/cpu/tegra2-common

Allen Martin
2012-05-10T07:02:19Z

In preparation for splitting out the armv4t code from tegra2, move the
tegra2 SoC code to arch/arm/cpu/tegra2-common. This code will be
compiled armv4t for the arm7tdmi and armv7 for the cortex A9.
