Sami Mujawar ef4cf3d88d MdePkg/ArmTrngLib: Add NULL instance of Arm TRNG Library
Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668)

The Arm True Random Number Generator (TRNG) library defines an
interface to access the entropy source on a platform. On platforms
that do not have access to an entropy source, a NULL instance of
the TRNG library may be useful to satisfy the build dependency.

Therefore, add a NULL instance of the Arm TRNG library.

Li, Zhihao 8079d4dc4f MdePkg: add SmmCpuRendezvousLib.h and SmmCpuRendezvousLibNull implement.
REF? https://bugzilla.tianocore.org/show_bug.cgi?id=3912

UefiCpuPkg define a new Protocol with the new services
SmmWaitForAllProcessor(), which can be used by SMI handler
to optionally wait for other APs to complete SMM rendezvous in
relaxed AP mode.

VariableSmm and VariableStandaloneMM driver in MdeModulePkg need
to use this services but MdeModulePkg can't depend on UefiCpuPkg.

Thus, the solution is moving SmmCpuRendezvouslib.h from UefiCpuPkg
to MdePkg and creating SmmCpuRendezvousLib NullLib version
implementation in MdePkg as dependency for the pkg that can't
depend on UefiCpuPkg.

Yu Pu d4eef3fe7c MdePkg: Add CpuLib to module INFs that depend on UefiCpuLib.
There are two libraries: MdePkg/CpuLib and UefiCpuPkg/UefiCpuLib and
UefiCpuPkg/UefiCpuLib will be merged to MdePkg/CpuLib. To avoid build
failure, add CpuLib dependency to all modules that depend on UefiCpuLib.

Dandan Bi 98ff7e3c63 MdePkg: Add MdeLibs.dsc.inc file to MdePkg
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3246

MdeLibs.dsc.inc is added for some default libraries provided by MdePkg.
Platform can include MdeLibs.dsc.inc file to avoid some potential
incompatible changes to platform dsc file in future.

Only add RegisterFilterLib into it as the first version of MdeLibs.dsc.inc.
Can update and maintain MdeLibs.dsc.inc gradually later.

"MdeLibs.dsc.inc" for the [LibraryClasses*] section(s)
