2  * linux/arch/arm/mach-omap1/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.
