* Description:

* Since we don't do anything unusual at the moment, this function
* accomplishes nothing except avoid a missing-function linker error if

*
* Input Parameters:
* cmd - IOCTL command being requested.
* arg - Arguments for the IOCTL.
*
* Returned Value:
* we don't yet support any boardctl IOCTLs. This function always returns
* -ENOTTY which is the standard IOCTL return value when a command is not
* supported
