On Tegra2 the AVP runs the normal U-Boot code to a point, then halts and the A9 takes over. The current Tegra2 boot path is fairly complex, since it has a separate path and code for the Cortex-A9 and the AVP. In fact, they can largely execute the same code path.
This series cleans up this logic and removes some parallel and un-needed code.
Note this series is rebased against master, with the following patches added, which should be picked up first:

Changes in v2: - Move Makefile armv4t flags from arch/arm/lib to Tegra's config.mk - Keep Tegra's config.mk file around so we can set the armv4t flags
Changes in v4: - Revert series to version 1 - Rebase against master - Use cp_init_cp15() name consistently
