+  EFI SMM Base Helper Ready Protocol.
+
+  This UEFI protocol is produced by the SMM Base Helper SMM driver to provide
+  a Framework SMST to the SMM Base Thunk driver. This protocol is also an indicator
+  that the SMM Base Helper SMM driver is ready in SMRAM for communication with
+  the SMM Base Thunk driver.
