Thanks, this is actually a very good idea. In fact, we recently restored
earlyprintk support on SuperH which got disabled by accident [1], so I
would have an opportunity to use it right away.

Do you have maybe any clue as for how to update u-boot on this machine?

Might be a good idea to start from the most recent version that is supported
on this target. I assume the "erase" command will erase the flash. But there
doesn't seem to be a "program" command.
