Well, I hacked head.S recently to fix booting with LPAE and BE8, but I was
unable to test early console since I was using virtio-console. It could be
that the page table entries mapping the uart aren't quite right, but no
obvious issues jump out from looking at the code.
How much visibility do you have on your platform? Can you take a look at the
page table entries and check they look ok please?
Cheers,
Will
