 *  Description          :
 *
 * Board Support Package for Trimedia peripherals. This particular file supports
 * the Philips dtv ref3(gomad) board. The purpose of this file is to define
 * philips_dtv_ref3_config. This board config structure will be included in a
 * table in boardcfg.c
 *
 * This file also defines many of the functions and structures which are
 * referenced in the board config structure.
 *
 * Revision                 :
