The interface proposed in this patch series intends to provide an abstraction layer for DXE drivers to request certain memory regions to be accessible from inside MM environment that applies total memory blockage.
This abstraction could pave way for models such as Standalone MM to manage memory resources without having knowledge of DXE memory map inside MM environment. Example usages of it can be NVS region in Tcg2Smm and runtime variable cache regions in VariableSmmRuntimeDxe.
