 * @section Introduction
 *
 * @subsection xxx Overview
 *
 * The XMC takes on the following roles:
 * 		a) UMC to VBusM conversion
 * 		b) Shared memory access path
 * 		c) Prefetch support
 * 		d) Address extension/translation
 * 		e) Memory protection for addresses outside CGEM eg. MSMC RAM or EMIF
 *
 * @subsection References
 *   -# XMC User's Guide
 *
 * @subsection Assumptions
 *    The abbreviations XMC, xmc and Xmc have been used throughout this
 *    document to refer to CGEM eXtended Memory Controller
