* MdePkg: Remove "assert" from SmmCpuRendevousLibNull.cZhihao Li2022-06-131-1/+0
| | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3931 Some drivers will break down when they use SmmWaitForAllProcessor() which from SmmCpuRendezvousLibNull.c. Removing the code "ASSERT(False)" will make consumer work normally if they keep default setting for sync mode.

* MdePkg: add SmmCpuRendezvousLib.h and SmmCpuRendezvousLibNull implement.Li, Zhihao2022-05-092-0/+55
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.
