+ * Name: board_initialize
+ *
+ * Description:
+ *   If CONFIG_BOARD_INITIALIZE is selected, then an additional
+ *   initialization call will be performed in the boot-up sequence to a
+ *   function called board_initialize().  board_initialize() will be
+ *   called immediately after up_initialize() is called and just before the
+ *   initial application is started.  This additional initialization phase
+ *   may be used, for example, to initialize board-specific device drivers.
