So this hints at the fact that this firmware is board specific. Is that
correct ? If so, shouldn't we plan on making the Git repo and its
version configurable ?

I mean, what are the chances that for some random ZynqMP board, your
Github repo will contain the appropriate firmware file ?

Generally speaking, it's a bit annoying that we can't build this from
source. I understand it needs a Microblaze toolchain, so it's very
difficult to integrate in Buildroot :-/

Best regards,

Thomas
