OvmfPkg/RiscVVirt: Override for RISC-V CPU Features
...
This PCD provides a way for platform to override any
HW features that are default enabled by previous stages
of FW (like OpenSBI). For the case where previous/prev
stage has disabled the feature, this override is not
useful and its usage should be avoided.

MdeModulePkg: Duplicate BaseRngLibTimerLib to MdeModulePkg
...
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504
The BaseRngLibTimerLib allows to generate number based on a timer.
This mechanism allows to have a basic non-secure implementation
for non-production platforms.
To bind and identify Random Number Generators implementations with
a GUID, an unsafe GUID should be added. This GUID cannot be added
to the MdePkg unless it is also added to a specification.
To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to
the MdeModulePkg. This will allow to define an unsafe Rng GUID
in a later patch in the MdeModulePkg.
The MdePkg implementation will be removed later. This allows to give
some time to platform owners to switch to the MdeModulePkg
implementation.
