+  SMM Ready To Lock protocol as defined in the PI 1.2 specification.
+
+  This SMM protocol indicates that SMM is about to be locked.
+  This protocol is a mandatory protocol published by the SMM Foundation code when the system is 
+  preparing to lock SMM. This protocol should be installed immediately after
+  EFI_END_OF_DXE_EVENT_GROUP_GUID with no intervening modules dispatched.
