 * Definitions is as per the following format
 * #define <PART>_GPMC_CONFIG<x> <value>
 * Where:
 * PART is the part name e.g. STNOR - Intel Strata Flash
 * x is GPMC config registers from 1 to 6 (there will be 6 macros)
 * Value is corresponding value
 *
 * For every valid PRCM configuration there should be only one definition of
 * the same. if values are independent of the board, this definition will be
 * present in this file if values are dependent on the board, then this should
 * go into corresponding mem-boardName.h file
 *
 * Currently valid part Names are (PART):
 * M_NAND - Micron NAND
