Does this add support for a 32-bit or a 64-bit U-Boot? Since T210 is a 
64-bit CPU I would have expected a 64-bit U-Boot, yet:

a)

arch/arm/Kconfig contains:

config TEGRA
...
         select CPU_V7

and this patch doesn't modify that.

b)

I can built an executable with these patches applied (after manually 
fixing up some merge problems) with an ARMv7 compiler, but not with an 
ARMv8 compiler.

I think that means this is a 32-bit port. We need a 64-bit port.
