| 22 | * PART is the part name e.g. STNOR - Intel Strata Flash |
| 23 | * x is GPMC config registers from 1 to 6 (there will be 6 macros) |
| 24 | * Value is corresponding value |
| 25 | * |
| 26 | * For every valid PRCM configuration there should be only one definition of |
| 27 | * the same. if values are independent of the board, this definition will be |
| 28 | * present in this file if values are dependent on the board, then this should |
| 29 | * go into corresponding mem-boardName.h file |
| 30 | * |
| 31 | * Currently valid part Names are (PART): |
| 32 | * M_NAND - Micron NAND |
| 33 | * STNOR - STMicrolelctronics M29W128GL |
