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.
