+ The entry point of PE/COFF Image for a Standalone MM Driver.
+
+ This function is the entry point for a Standalone MM Driver.
+ This function must call ProcessLibraryConstructorList() and
+ ProcessModuleEntryPointList().
+ If the return status from ProcessModuleEntryPointList()
+ is an error status, then ProcessLibraryDestructorList() must be called.
+ The return value from ProcessModuleEntryPointList() is returned.
+ If _gDriverUnloadImageCount is greater
+ than zero, then an unload handler must be registered for this image and
+ the unload handler must invoke ProcessModuleUnloadList().
+ If _gMmRevision is not zero and SystemTable->Hdr.Revision is
+ less than _gUefiDriverRevison, then return EFI_INCOMPATIBLE_VERSION.
+
+ @param ImageHandle The image handle of the Standalone MM Driver.
+ @param SystemTable A pointer to the EFI System Table.
+
+ @retval EFI_SUCCESS The Standalone MM Driver exited normally.
+ @retval EFI_INCOMPATIBLE_VERSION _gMmRevision is greater than
+ SystemTable->Hdr.Revision.
+ @retval Other Return value from
+ ProcessModuleEntryPointList().
