A new Arm standard DEN0115A specifies how
platforms that don't have standard ECAM can
use the firmware to handle config read/write
operations. This is mostly implemented in TFA
but UEFI needs to assure that there is a
description of the root complex in the ACPI
namespace.

This set adds that description based on
a new menu item which toggles between XHCI
platform description and PCIe via a BDS
menu selection on the RPi4. The CM4 is really
the platform that needs this as it has a PCIe
slot. On that platform PCIe is enabled by default.

Jeremy Linton (5):
  Platform/RaspberryPi: Add XHCI/PCI selection menu
  Platform/RaspberryPi: break XHCI into its own SSDT
  Platform/RaspberryPi: Add PCIe SSDT
  Silicon/Broadcom/Bcm27xx: Tweak PCIe for CM4
  Platform/RaspberryPi: Enable NVMe boot on cm4
