This series patches are generate to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS requirement.
Before this series patches, the DXE or OS module can use any non-SMM memory as communication buffer to exchange data with SMM agent. Microsoft WSMT table has requirement to support fixed communication buffer - so that SMM agent can only support communication buffer with type EfiReservedMemoryType/ EfiRuntimeServicesCode/EfiRuntimeServicesData/EfiACPIMemoryNVS, which will not be used by OS during runtime. So we clean up all SMM handler to only use these memory regions for SMM communication, and enhance check in SmmMemLib to catch the violation. This series patches are validated on real platforms with SMM enabled. This series patches are validated on OVMF ia32-x64 with SMM enabled.
