+/* C.11.1. Introduction */
+/* This module provides the platform specific entry and fail processing. The _plat__RunCommand()
+   function is used to call to ExecuteCommand() in the TPM code. This function does whatever
+   processing is necessary to set up the platform in anticipation of the call to the TPM including
+   setup for error processing. */
+/* The _plat__Fail() function is called when there is a failure in the TPM. The TPM code will have
+   set the flag to indicate that the TPM is in failure mode. This call will then recursively call
+   ExecuteCommand() in order to build the failure mode response. When ExecuteCommand() returns to
+   _plat__Fail(), the platform will do some platform specif operation to return to the environment
+   in which the TPM is executing. For a simulator, setjmp/longjmp is used. For an OS, a system exit
+   to the OS would be appropriate. */

+/* C.11.3.1. _plat__RunCommand() */
+/* This version of RunCommand() will set up a jum_buf and call ExecuteCommand(). If the command
+   executes without failing, it will return and RunCommand() will return. If there is a failure in
+   the command, then _plat__Fail() is called and it will longjump back to RunCommand() which will
+   call ExecuteCommand() again. However, this time, the TPM will be in failure mode so
+   ExecuteCommand() will simply build a failure response and return. */
