+ * Name: board_led_initialize

+ * Description:

+ *   things as, for example, configure GPIO pins to drive the LEDs and also
+ *   putting the LEDs in their correct initial state.
+ *
+ *   In most architectures, board_led_initialize() is called fromo board-
+ *   specific initialization logic.  But there are a few architectures where
+ *   this initialization function is called from shared chip logic.
+ *
+ * Input Parameters:
+ *   None
+ *
+ * Returned Value:
+ *   None
