* 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.
