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.
The usage in VariableSmmRuntimeDxe to support runtime variable cache is included in this patch series. The usage in MM instance of Tcg2 to unblock NVS region is added after separating the module into Tcg2Acpi and Tcg2 MM to support StandaloneMm.
