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! Arnd
