So I've given this a go, and the basics (serial) worked
out of the box (thanks for that!) after performing the
memory-map change you described in your reply to patch 1.
However, I don't get anything on the PCIe front:
U-Boot> pci enum
PCIe BRCM: link down
PCIe BRCM: link down
despite having an nvme device connected and enabled
(the RPi kernel finds it).
I'm guessing I must be missing something. How did you
test PCIe?
No, you are not missing anything. I have not tested it
for real. That is why I said "it seems". Sorry.
Yesterday I started looking more closely at what's missing
and unfortunately a lot more changes are needed.
Ah, fair enough. I was slightly surprised that it appeared
to be working out of the box, which would have been a first
on the ARM side...
Happy to test whatever patches you come up with!
Thanks,
M.
