At the moment we use the arch/arm directory for arm64 boards as well, so the Makefile will pick up the "arm" name for the architecture to use for tagging binaries in U-Boot image files. Differentiate between the two by looking at the CPU variable being defined to "armv8", and use the arm64 architecture name on creating the image file if that matches.

Why is this important? To know the state you have to be in for SPL->U-Boot transition later?
Yes.
Why didn't anyone else stumble over this yet? Because nobody's using SPL?
Given the warnings and bugs I found when I compiled the SPL for 64 bit I'd assume the latter.
But I was asking this question myself already. Apparently everyone just hacked their firmware chain to live with "arm" in there, APM being a prominent example.
So given this I am a bit wary about the implication of this patch, I hope that people holler if this breaks their platform (and then fix that instead of hacking U-Boot again).
Cheers, Andre.
