 *
 * @section Introduction
 *  The External Memory Interface (EMIF) is a TI developed re-usable IP component 
 *  targeted for SOC designs. The EMIF is a VBUSM slave peripheral providing an 
 *  interface to a wide variety of DDR SDRAM. This memory controller is a soft 
 *  macro and must be used with the DDR PHY hard macros to interface to the 
 *  DDR SDRAM.
