/****************************************************************************
* 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.
