+// [TAG] EIP119036.2
+// [Category] Bug Fix
+// [Severity] Important
+// [Symptom] SecureFlash fail with ME "AT disable"
+// [RootCause] SMM HECI not installed if ME is disabled by FDO Jumper.
+// [Solution] Added check SmmHeci protocol before AtGetTimerInfo call.

+// [TAG] EIP119036.1
+// [Category] Bug Fix
+// [Severity] Important
+// [Symptom] SecureFlash fail with ME ¡§AT disable¡¨
+// [RootCause] HECI returns "UNSUPPORTED" not "TIMEOUT" if ME is
+// disabled.
+// [Solution] Added check ME Mode and AT state before AtGetTimeInfo
+// call.
