 * \brief Dummy implementations of optional board support package IO functions allowing 
 * platforms to selectively support only needed functionality.  These are placeholder
 * routines that will satisfy references from other code to avoid link errors, but they 
 * do not peform any actual operations.
 *
 * See chirp_bsp.h for descriptions of all board support package interfaces, including 
 * details on these optional functions.
