1 | /* |
| 2 | * linux/arch/arm/mach-omap/board-generic.c | |
| 3 | * | |
| 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. | |
