To be absolutely clear, the above are not u-boot commands?  You have
to use setenv and quote the parameters?

Second question: In the tarball you previously posted, the .img file
is called 'mp30ar0_media.img' (not 'mp30ar0_tianocore_media.img').  Is
that correct or is there a newer version somewhere?

Third question: How do I set the MAC address in this TianoCore?
RHEL booted up with MAC 00:00:00:00:00:00 which meant nothing else
worked of course.
