[PATCH] Platforms/AMD/Styx: remove A PRIORI FDF sections for dynamic PCDs - Linaro-uefi

28 Apr 2016

The default PcdLib resolution supports dynamic PCDs, and to do so, it
depends on dynamic PCD related PPIs and protocols that are produced by
the PEI and DXE versions of Pcd.inf, respectively. However, since these
inherit this default resolution, Pcd.inf depends on protocols it produces
itself, and can only be loaded forcefully using A PRIORI sections in the
FDF.
So instead, make Pcd.inf use the NULL PcdLib instance, so that it can be
dispatches in the normal way.
