/*
 * linux/arch/arm/mach-omap1/board-generic.c
 *
 * Modified from board-innovator1510.c
 *
 * Code for generic OMAP board. Should work on many OMAP systems where
 * the device drivers take care of all the necessary hardware initialization.
 * Do not put any board specific code to this file; create a new machine
 * type if you need custom low-level initializations.
