Laszlo Ersek 65bb13b0fd ArmVirtualizationPkg/VirtFdtDxe: parse "pci-host-ecam-generic" properties 
In the Linux kernel tree,
"Documentation/devicetree/bindings/pci/host-generic-pci.txt" describes the
device tree bindings of a Generic PCI host controller.

Recent QEMU patches from Alexander Graf implement such a controller on the
"virt" machine type of qemu-system-(aarch64|arm):

  pcie@10000000 {
    //
    //                    (devfn<<8, 0, 0)  PCI irq
    //                    ----------------  -------
    interrupt-map-mask = <0x1800 0x0 0x0    0x7>;

    //                                        gic      irq
    //               (devfn<<8, 0, 0)  pin+1  phandle  (type, nr, level)
    //               ----------------  -----  -------- -----------------
    interrupt-map = <   0x0 0x0 0x0    0x1    0x8001   0x0 0x3 0x4

    #interrupt-cells = <0x1>;

    //

    ranges = <0x1000000  0x0        0x0  0x0 0x3eff0000  0x0    0x10000
              0x2000000  0x0 0x10000000  0x0 0x10000000  0x0 0x2eff0000>;

    //
    //     PCIe config     PCIe config
    //     space base      space size
    //     --------------  -------------
    reg = <0x0 0x3f000000  0x0 0x1000000>;

    //
    // allowed bus numbers; inclusive range
    //
    bus-range = <0x0 0xf>;

    #size-cells = <0x2>;
    #address-cells = <0x3>;
    device_type = "pci";
    compatible = "pci-host-ecam-generic";
  };

Parse those properties of the compatible="pci-host-ecam-generic" node into
PCDs that are relevant for PCI enumeration in edk2:

- gEfiMdePkgTokenSpaceGuid.PcdPciExpressBaseAddress controls
  MdePkg/Library/BasePciExpressLib,

- gEfiMdeModulePkgTokenSpaceGuid.PcdPciDisableBusEnumeration controls
  OvmfPkg/AcpiPlatformDxe at this point,

- the rest have been introduced earlier in this patchset, and will control
  PCI range checks and translation.
