 * Name: board_ioctl
 *
 * Description:
 *   The "landing site" for much of the boardctl() interface. Generic board-
 *   control functions invoked via ioctl() get routed through here.
 *
 *   Since we don't do anything unusual at the moment, this function
 *   accomplishes nothing except avoid a missing-function linker error if
 *   CONFIG_BOARDCTL_IOCTL is selected.
 *
 * 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
 *
