Which machine did you hit this on? Is this on hardware or in qemu?
qemu, as always. borzoi, spitz, terrier, tosa, z2, and sx1 fail. Also, I just noticed that the failure is not always the same. z2 fails to boot from initrd, and sx1 fails to boot completely.
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.
I'll do another round of bisects.
Thanks!
