   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.
