This patch series is preparatory work to make PCI passthrough code non-x86
specific.

Rahul Singh (4):
  xen/ns16550: solve compilation error on ARM with CONFIG_HAS_PCI
    enabled.
  xen/pci: Introduce new CONFIG_HAS_PCI_ATS flag for PCI ATS
    functionality.
  xen/pci: Move x86 specific code to x86 directory.
  xen/pci: solve compilation error when memory paging is not enabled.

Do you have a simple patch I could use to test the compilation on ARM?
Even just a hack to help me review the series?

Right now I can only test that the compilation on x86 is unbroken.

Thanks!
