With simple exposure of MMFG, ioport window, mmio window and an IRQ line we can successfully create a workable PCIe host bridge that can be mapped anywhere and only needs to get described to the OS using whatever means it likes. This patch implements such a "generic" host bridge. It handles 4 legacy IRQ lines. MSIs need to be handled external to the host bridge. This device is particularly useful for the "pci-host-ecam-generic" driver in Linux.
