[Qemu-devel] [PATCH v3 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
v2 -> v3:
- Update patch description
- Increase ecam region to full size
- Expose number of irqs via define
- Update header description
- Update host bridge qom description string
- Use new Red Hat PCIe host bridge PCI ID
- Coding style fixes
- Map ECAM space via alias to limit its size
- Increase ECAM size to 16 buses
- Use GPEX IRQ number define
- Align ECAM region, Document region allocation better
- Move interrupt-map into irq map function
- s/FDT_PCI_RANGE_TYPE/FDT_PCI_RANGE_TYPE_MASK/
