ArmVirtualizationPkg/PciHostBridgeDxe: clone from PcAtChipsetPkg MdeModulePkg/Bus/Pci/PciBusDxe depends on EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL and EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL. Here we clone the driver that produces these from PcAtChipsetPkg, with the following immediate changes: - a new FILE_GUID is generated; - the assembly-language Ia32 / X64 specific IoFifo "accelerators" are not copied, and their client code (which would be dead code anyway) is removed; - UNI files are not copied: they are used in conjunction with the UEFI Packaging Tool (UPT), but the driver under ArmVirtualizationPkg will not be part of UDK.

ArmVirtualizationPkg/PciHostBridgeDxe: set Root Bridge apertures from PCDs Our PciHostBridgeDxe module creates one root bridge on the one and only host bridge. The resource apertures of the root bridge (bus range, IO space, MMIO space) are configured with the "mResAperture" array, which at the moment carries static values inherited from PcAtChipsetPkg. Set the array as first thing from the PCDs that we parsed from the device tree.

ArmVirtualizationPkg/PciHostBridgeDxe: abort if there's no PCI host bridge If VirtFdtDxe found no PCI host in the DTB, then the config space base address will be left at zero -- the default is set in the DSC --, and we should exit PciHostBridgeDxe immediately. This causes gEfiPciRootBridgeIoProtocolGuid not to be installed, which in turn prevents MdeModulePkg/Bus/Pci/PciBusDxe from binding (see PciBusDriverBindingSupported()).

ArmVirtualizationPkg/PciHostBridgeDxe: MMIO aperture must not be uncached Quite non-intuitively, we must allow guest-side writes to emulated PCI MMIO regions to go through the CPU cache, otherwise QEMU, whose accesses always go through the cache, may see stale data in the region. This change makes no difference for QEMU/TCG, but it is important for QEMU/KVM, at the moment. Because gDS->SetMemorySpaceAttributes() is ultimately implemented by EFI_CPU_ARCH_PROTOCOL.SetMemoryAttributes() -- see "MdeModulePkg/Core/Dxe/Gcd/Gcd.c" and "ArmPkg/Drivers/CpuDxe/" -- we add the CPU architectural protocol to the module's DepEx.
