 * PART is the part name e.g. M_NAND - Micron Nand Flash
 * x is GPMC config registers from 1 to 7 (there will be 7 macros)
 * Value is corresponding value
 *
 * For every valid PRCM configuration there should be only one definition of

 *
 * The following values are optimized for improving the NAND Read speed
 * They are applicable and tested for Bosch Guardian Board.
 * Read Speeds rose from 1.5MiBs to over 7.6MiBs

 * Currently valid part Names are (PART):
