* Name: boardctl
|
|
*
|
|
* Description:
|
|
* In a small embedded system, there will typically be a much greater
|
|
* interaction between application and low-level board features. The
|
|
* canonically correct to implement such interactions is by implementing a
|
|
* character driver and performing the interactions via low level ioctl
|
|
* calls. This, however, may not be practical in many cases and will lead
|
|
* to "correct" but awkward implementations.
|
|
*
|
|
* boardctl() is non-standard OS interface to alleviate the problem. It
|
|
* basically circumvents the normal device driver ioctl interlace and allows
|
|
* the application to perform direction IOCTL-like calls to the board-specific
|
|
* logic. In it is especially useful for setting up board operational and
|
|
* test configurations.
|
|
*
|
|
* Input Parameters:
|
|
* cmd - Identifies the board command to be executed
|
|
* arg - The argument that accompanies the command. The nature of the
|
|
* argument is determined by the specific command.
|
|
*
|
|
* Returned Value:
|
|
* On success zero (OK) is returned; -1 (ERROR) is returned on failure
|
|
* with the errno variable to indicate the nature of the failure.
