+ 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
