Revision: 16736
http://sourceforge.net/p/edk2/code/16736
Author: vanjeff
Date: 2015-02-04 03:22:44 +0000 (Wed, 04 Feb 2015)
Log Message:
-----------
Handle TPM device error and avoid deadloop in BDS.
If TPM error happens, set TPM flag to NOT present, so that trusted boot patch
is disabled.
Also report status code for failure, so that platform may register handler to
apply policy like force system reset, or disable TPM permanently.
(Sync patch r16598 from main trunk.)
