+ 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.
