[Qemu-devel] [edk2 PATCH 00/12] consume fw_cfg boot order in ArmVirtualizationQemu

[Laszlo Ersek <lersek@redhat.com>]

The series
- adds a DTB- and MMIO-based fw_cfg client library to the
  ArmVirtualizationQemu platform (patches #1 and #2),

- makes OvmfPkg's OpenFirmware to UEFI devpath translation logic
  reusable for the ArmVirtualizationQemu platform, making the virtio-pci
  specific bits conditional (patches #5 and #6),

- introduces (similarly conditional) coverage for virtio-mmio device
  paths (patches #7, #8, #9, #10),

- introduces a new Intel BDS boot policy for ArmVirtualizationQemu that
  considers the QEMU boot order, similarly to OVMF (patches #3, #4,
  #11),

- somewhat independently, ensures that the UEFI shell is always present
  as a boot option (patch #12).

The patches are interleaved in a "demand driven" order, showing the
dependencies between ArmVirtualizationPkg and OvmfPkg.
ArmVirtualizationPkg takes the edges, providing the low level fw_cfg
client service and consuming the top-level feature, whereas OvmfPkg sits
in the middle, consuming the fw_cfg capability and providing the boot
order logic.

The patchset compiles at each step, for OvmfPkg, for
ArmVirtualizationPkg without -D INTEL_BDS, and for ArmVirtualizationPkg
with -D INTEL_BDS.
