Actually VersatilePB hardware supports PCI I/O just fine.
I've tested a SATA card and had PCI memory, I/O, interrupts
and DMA working on a PB926. The problems are:
(1) The Linux versatile PCI code is badly broken; Arnd
Bergmann wrote patches to fix this last year but I don't
think they ever got merged upstream
(2) The QEMU versatile PCI model has been written and
tested against the broken Linux code, so (a) issues like this
one with I/O and (b) if you use the fixed Linux code it
doesn't work on the qemu models...
