 *  Description              :
 *
 * Board Support Package for Trimedia peripherals. This particular file supports
 * the Philips dtv board. The purpose of this file is to define
 * philips_dtv_ttr_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.
