+  DXE SMM Ready To Lock protocol introduced in the PI 1.2 specification.
+
+  According to PI 1.4a specification, this UEFI protocol indicates that
+  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 PI platform code.
+  This protocol in tandem with the End of DXE Event facilitates transition
+  of the platform from the environment where all of the components are
+  under the authority of the platform manufacturer to the environment where
+  third party extensible modules such as UEFI drivers and UEFI applications
+  are executed. The protocol is published immediately after signaling of the
+  End of DXE Event. PI modules that need to lock or protect their resources
+  in anticipation of the invocation of 3rd party extensible modules should
+  register for notification on installation of this protocol and effect the
+  appropriate protections in their notification handlers. For example, PI
+  platform code may choose to use notification handler to lock SMM by invoking
+  EFI_SMM_ACCESS2_PROTOCOL.Lock() function.
