  /*
   * 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.
   *
