thanks for your interest in contributing and for reaching out!
As Peter already mentioned, you would need to send a patch, as generated
by "git format-patch". "git send-email" would help you with sending this
out.

But actually I sent a small series already last week:
https://lore.kernel.org/u-boot/20231114013106.31336-1-andre.przywara@arm.com/

If you could apply these patches and test it on your board, I'd be
grateful. If it works for you and you are happy, please reply to patch 3/3
and add a "Tested-by: Your Name <your at email.com>" line.
For instructions how to reply, check "Reply instructions" at the end of
that mailing list archive web page above.

I was just waiting for confirmations by other people before merging it.

Cheers,
Andre
