   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.
