[Qemu-devel] [PATCH v2 0/4] ARM: Add support for a generic PCI Express host bridge |

Linux implements a nice binding to describe a "generic" PCI Express host bridge
using only device tree.
This patch set adds enough emulation logic to expose the parts that are
"generic" as a simple sysbus device and maps it into ARM's virt machine.
With this patch set, we can finally spawn PCI devices on ARM VMs. I was able
to have a fully DRM enabled virtual machine with VGA, e1000 and XHCI (for
keyboard and mouse) up and working.
It's only a small step for QEMU, but a big step for ARM VM's usability.
v1 -> v2:
- Add documentation links
- Remove mmio_window_size
- Add define for pci range types
- Use 4 PCI INTX IRQ lines

pci: Split pcie_host_mmcfg_map()
pci: Add generic PCIe host bridge
arm: Add PCIe host bridge in virt machine
pci: Move PCI VGA to pci.mak
