Changes in v2:
- The DTB bindings have been updated ("standardized") for patch #1.
(Changes are mentioned there in a bit more detail.)
V1 was posted at
<http://thread.gmane.org/gmane.comp.bios.tianocore.devel/11493/focus=11497>.
Quoting the blurb:
> 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.
