| 4 | * Modified from board-innovator1510.c |
| 5 | * |
| 6 | * Code for generic OMAP board. Should work on many OMAP systems where |
| 7 | * the device drivers take care of all the necessary hardware initialization. |
| 8 | * Do not put any board specific code to this file; create a new machine |
| 9 | * type if you need custom low-level initializations. |
