That's correct AFAICT.

Are you able to build working u-boot proper from recent sources?

I know u-boot SPL misses critical parts, but I was told that u-boot
proper should have everything. Only... I was not able to get it to
work. [I'm attempting to load recent u-boot from patched/old u-boot; I
know this is not exactly recommended, but due to spl/proper split, it
should work AFAIK... and does for old versions.]

Any ideas?

Thanks,
