[PATCH v6 0/5] Kconfig for PCI passthrough on ARM

[Stewart Hildebrand <stewart.hildebrand@xxxxxxx>]

There are multiple series in development/review [1], [2] that will benefit from
having a Kconfig option for PCI passthrough on ARM. Hence I have sent this
series independent from any other series.

v5->v6:
* address feedback in individual patches

v4->v5:
* add [FUTURE] tag to ("xen/arm: enable vPCI for dom0")
* address feedback in individual patches

v3->v4:
* rename ("xen/arm: pci: plumb xen_arch_domainconfig with pci info")
  to ("xen/vpci: move xen_domctl_createdomain vPCI flag to common")
* fold ("xen/arm: make has_vpci() depend on d->arch.has_vpci")
  into ("xen/vpci: move xen_domctl_createdomain vPCI flag to common")
* split ("xen/arm: enable vPCI for domUs") into separate hypervisor and
  tools patches

v2->v3:
* add ("xen/arm: pci: plumb xen_arch_domainconfig with pci info")
* rename ("xen/arm: make has_vpci depend on CONFIG_HAS_VPCI")
      to ("xen/arm: make has_vpci() depend on d->arch.has_vpci")
* add ("xen/arm: enable vPCI for dom0")

v1->v2:
* add ("[FUTURE] xen/arm: enable vPCI for domUs")
