Hi Tom,
I've got one of these shield things - it is a seriously cool piece of hardware. I've have to read a bit about what is it for.
So, any idea where to find a UART and recovery button?
Regards, Simon

Yes, it's a 32-bit T210 U-Boot. T210 supports both AARCH32 and AARCH64.
A 64-bit build will follow, but I haven't figured out how to meld the 32-bit AVP SPL portion/build with the 64-bit CPU portion/build in one clean build command, so I'm building them separately and then fusing them together in a separate script. If anyone has ideas on how to generate a hybrid 32-bit (AVP)/64-bit (A57) U-Boot binary in one fell swoop, I'm all ears. :)

Adds support for Tegra210 SoC and P2571 NVIDIA board. Largely based on T124/Venice2. This is a baseline patchset - more will follow to make things more T210- specific as P2571 peripherals/devices are brought up.
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.
