tegra2: Simplify tegra_start() boot path The Tegra2 boot path is more complicated than it needs to be. Since we want to move to building most of U-Boot with ARMv7 and only a small part with ARMv4T (for AVP) it should be as simple as possible. This makes tegra2_start() into a simple function which either does AVP init or A9 init depending on which core is running it. Both cores now following the same init path, beginning at _start, and the special Tegra2 boot path code is no longer required. Only two files need to be built for ARMv4T, and this is handled in the Tegra2 CPU Makefile. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

tegra: add enterrcm command Tegra's boot ROM supports a mode whereby code may be downloaded and flash programmed over a USB connection. On dev boards, this is typically entered by holding down a "force recovery" button and resetting the CPU. However, not all boards have such a button (one example is the Compulab Trimslice), so a method to enter RCM from software is useful. This change implements the command "enterrcm" to do this, and enables it for all Tegra boards by default. Even on boards other than Trimslice, controlling this over a UART may be useful, e.g. to allow simple remote control without the need for mechanical button actuators, or hooking up relays/... to the button.
