/* For the given Command Register (CR) and Features Register (FR), attempts
 * to construct a string that describes the contents of the Status
 * Register (ST) and Error Register (ER).  The caller passes the string
 * buffer and the return value is a pointer to this string.  If the
 * meanings of the flags of the error register are not known for the given
 * command then it returns NULL.
 *
 * The meanings of the flags of the error register for all commands are
 * described in the ATA spec and could all be supported here in theory.
 * Currently, only a few commands are supported (those that have been seen
 * to produce errors).  If many more are to be added then this function
 * should probably be redesigned.
