This v3 now fully gets rid of the VirtFdtDxe kludge, by moving its
functionality to its various clients that access PCDs or protocols supplied
by it.
Changes since v2:
- dropped the patches implementing the protocol definition, the FdtClientDxe
implementation and the handling of the GIC, PSCI, timer, fw_cfg and PCI
device tree nodes since they have now been merged (thanks Laszlo)
- renamed ArmVirtRtcFdtClientLib to ArmVirtPL031FdtClientLib since it is
specific to PL031
- handle missing arm,pl031 DT node gracefully (as before), rather than blowing
up the firmware by returing failure from a library constructor
- some general cleanup of INFs, i.e., add missing library dependencies, remove
declared false dependencies
Changes since v1:
- merged two patches related to Pcd.inf's dependency on itself
- incorporated early feedback from Laszlo
- tweaked the protocol to support virtio,mmio DT node discovery
- split the remaining VirtFdtDxe functionality into XenioFdtDxe and
VirtioFdtDxe
- updated commit messages (where appropriate) to justify the conversion from
a A PRIORI DXE driver to a protocol dependency on the FDT client protocol
------ v1 blurb -------
This series addresses the cases where other DXE drivers rely on dynamic PCDs
populated by VirtFdtDxe, which requires it to execute first using an A PRIORI
declaration. Instead, this series moves the DT node parsing to the respective
users, using a new FDT client protocol which can be used in the various
depexes.
The next step is to split the remaining handling performed by VirtFdtDxe into
drivers appropriate for the platforms, i.e., virtio for QEMU and xeniommio for
Xen domU.
This is somewhat rough around the edges, but is mostly intended to elicit
discussion, and I fully expect these changes to make it into the tree looking
a lot different from this v1.
