This patch is intended to update the naming convention which U-boot mentions in
doc/README.kconfig. As we know that FU540-C000 has a U54-MC CPU core, I thought
of naming it as u54-mc and board name from fu540 to hifive_unleashed
which is the
actual case.

Unfortunately yes. Hence I raised a request in the cover letter for suggestions
accordingly.

I do remember using "git mv" here. Probably adding  '-M' (detect renames)
switch to git format-patch would have helped to include the renamed files
instead of delete and create information. Next time I will ensure to include it.
Thanks for pointing this.
