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 ATF
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.
Jeremy Linton (3):
rpi4: Add XHCI/PCI selection menu
rpi4/acpi/dsdt: break XHCI into its own SSDT
rpi4/acpi: Add PCIe SSDT
