 * 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.
