+ * Name: board_reset
+ *
+ * Description:
+ *   Reset board.  Support for this function is required by board-level
+ *   logic if CONFIG_BOARDCTL_RESET is selected.
+ *
+ * Input Parameters:
+ *   status - Status information provided with the reset event.  This
+ *            meaning of this status information is board-specific.  If not
+ *            used by a board, the value zero may be provided in calls to
+ *            board_reset().
+ *
+ * Returned Value:
+ *   If this function returns, then it was not possible to power-off the
+ *   board due to some constraints.  The return value int this case is a
+ *   board-specific reason for the failure to shutdown.
