[PATCH v2 0/4] hw/arm: xenpvh: Enable PCI for ARM PVH

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@amd.com>

Enable PCI on the ARM PVH machine. First we add a way to control the use
of buffered IOREQ's since those are not supported on Xen/ARM.
Finally we enable the PCI support.

I've published some instructions on how to try this including the work in
progress Xen side of the PVH PCI support:

Cheers,
Edgar

ChangeLog:

v1 -> v2:
* Change handle_ioreq from int to uint8_t.
* Fallback to legacy API if buffered ioreqs are enabled and also if
  the new API is not supported. Clarify with comments.
