I have applied, after doing some minor changes, see below.

Changed to just "riscv-pk needs ..."

Changed to just "riscv-pk"

For both changes: our policy is to try to stick to the upstream package
name in the Config.in prompt and comments.

I've added a missing blank line here.

I fixed a bit the indentation here.

Changed this to be on one single line.

And changed to:

	$(INSTALL) -D -m 0755 $(@D)/build/bbl $(BINARIES_DIR)/bbl

Thanks again for this contribution!
