+  DXE SMM Ready To Lock protocol introduced in the PI 1.2 specification.\r
+\r
+  According to PI 1.4a specification, this UEFI protocol indicates that\r
+  resources and services that should not be used by the third party code\r
+  are about to be locked.\r
+  This protocol is a mandatory protocol published by PI platform code.\r
+  This protocol in tandem with the End of DXE Event facilitates transition\r
+  of the platform from the environment where all of the components are\r
+  under the authority of the platform manufacturer to the environment where\r
+  third party extensible modules such as UEFI drivers and UEFI applications\r
+  are executed. The protocol is published immediately after signaling of the\r
+  End of DXE Event. PI modules that need to lock or protect their resources\r
+  in anticipation of the invocation of 3rd party extensible modules should\r
+  register for notification on installation of this protocol and effect the\r
+  appropriate protections in their notification handlers. For example, PI\r
+  platform code may choose to use notification handler to lock SMM by invoking\r
+  EFI_SMM_ACCESS2_PROTOCOL.Lock() function.\r

 \r
-  This protocol is a mandatory protocol published by the PI platform code prior to invoking any\r
-  3rd party content, including options ROM's and UEFI executables that are not from the platform manufacturer.\r
-  There is an associated event GUID that is signaled for the DXE drivers called EFI_END_OF_DXE_EVENT_GUID.\r

+  This protocol is a mandatory protocol published by SMM Foundation code.\r
+  This protocol is an SMM counterpart of the End of DXE Event.\r
+  This protocol prorogates End of DXE notification into SMM environment.\r
+  This protocol is installed prior to installation of the SMM Ready to Lock Protocol.\r
