/**
* @file
*
* HyperTransport features and sequence implementation.
*
* Implements the external AmdHtInitialize entry point.
* Contains routines for directing the sequence of available features.
* Mostly, but not exclusively, AGESA_TESTPOINT invocations should be
* contained in this file, and not in the feature code.
*
* From a build option perspective, it may be that a few lines could be removed
* from compilation in this file for certain options. It is considered that
* the code savings from this are too small to be of concern and this file
* should not have any explicit build option implementation.
