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.
