+/** @file
+  SMM Ready To Lock protocol introduced in the PI 1.2 specification.
+
+  According to PI 1.4a specification, this SMM protocol indicates that
+  SMM resources and services that should not be used by the third party
+  code are about to be locked.
+  This protocol is a mandatory protocol published by the SMM Foundation
+  code when the system is preparing to lock certain resources and interfaces
+  in anticipation of the invocation of 3rd party extensible modules.
+  This protocol is an SMM counterpart of the DXE SMM Ready to Lock Protocol.
+  This protocol prorogates resource locking notification into SMM environment.
+  This protocol is installed after installation of the SMM End of DXE Protocol.
