Instead, can you do something similar to tegra, which uses ARMv4t for SPL and ARMv7 for U-Boot proper?

You will need two different (cross-)compilers, so just setting some compiler options will not help. Besides compiling the SPL as 32-bit is only an option, the SPL also works as a pure 64-bit binary. And people expressed the wish of having the option of using both ways - at least for the time being.

Honestly, I have the feeling that this is the only thing that holds this serie back. Maybe you can send it without it first, we merge it, and then we work on the 32 bits SPL. That way, we don't delay everything else but the very last patch.

Thanks! Maxime
