In some ways, yes. In others, it made it easy to first get a SPL (AVP)
U-Boot up and printing its sign-on, and then having a base to work
from/debug A9 code for the second, CPU-init half.

WIP. There'll be an arch/arm/cpu/arm720t/tegra-common, an
arch/arm/cpu/armv7/tegra-common, and even an
arch/arm/cpu/tegra-common, plus an arch/arm/include/asm/arch-tegra to
hold common code & include files.
How those changes will be captured in a patchset (or 2) that show the
movement of the original Tegra20 files, then the copy/edit for Tegra30
is still to be seen.
Thanks,
Tom
