Add a tool that can generate GUIDs that match those generated internally
by U-Boot for capsule update fw_images.
Dynamic UUIDs in U-Boot work by taking a namespace UUID and hashing it
with the board model, compatible, and fw_image name.
This tool accepts the same inputs and will produce the same GUID as
U-Boot would at runtime.

Where is this tool used? Can you add a man page and test?
It currently doesn't have any users, it just allows for pre-generating
GUIDs ahead of time for a given board. It might be hooked up to vendor
tooling or some usecase like that.
I've somehow escaped learning Groff before now heh, I can give it a go
and write a test.
OK (just copy bits of mkimage.1 :-)
Right :D
Re the test, would this be something that binman would use? If so you
could put a test there.
This tool is just a wrapper for gen_uuid_v5() which we already test in
the dynamic UUID unit tests also introduced in this series. I don't
think it's necessary to additionally test this tool.
Kind regards,
Regards,
Simon
