I tried and it seems to work fine, resp. the only difference I could spot is that instead of 'crc32+ OK' it
prints some random ASCII characters in the last line before any U-Boot output:
[ 0.490] ## Checking hash(es) for Image opensbi ... crc32+ OK

Yes, exactly. I am just curious if it needs combining with some obscure vendor stuff.

Yes, I agree.
