commit message:
I currently need support for rsa-sha256 signatures in u-boot and found out that
the code for signatures is not very generic. Thus adding of different
hash-algorithms for rsa-signatures is not easy to do without copy-pasting the
rsa-code. I attached a patch for how I think it could be better and included
support for rsa-sha256. This is a fast first shot.
aditionally work:
- removed checkpatch warnings
- removed compiler warnings
- rebased against current head

This looks good to me. However, when running it I hit this crash?

Do you see this? Presumably not - I can dig a bit if you like?
No, I do not see this crash ... Hmm... you reply this error to the
4/8 patch of this series, but "fit_check_sign" is introduced in the
8/8 ... did you tried with all 8 patches applied?
Just tested with current head of U-Boot and I see no error:
