That's a lot of machines failing, I hope at least we got the same bugs more
than once here.

For the I/O space, I found now that PXA was not using the standard
virtual I/O address yet, but instead used a NULL-based offset.

I'm not entirely happy with this patch, but this is an outline of what
I think we need to fix that: https://pastebin.com/3nVgQsEw
This one is probably incomplete, at least it breaks sa1100 for now,
and it adds a bogus CONFIG_PCI dependency. I'm also not sure
in what way the last patch in the series triggers it, rather than the
one that removed mach/io.h.

I had sx1 booting in qemu at least, with the omap1 multiplatform series only.
If you have a custom config for this one, make sure you get the right
DEBUG_LL address.

Thanks!
