* particular board architecture.
|
|
*
|
|
* 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-specific reason for the failure to shutdown.
