79 * functionality common to all SYNCHRONIZE_CACHE command sizes.
81 * - setting the command register
82 * - setting the device head register
83 * - filling in fields in the SATI_TRANSLATOR_SEQUENCE object.
84 * For more information on the parameters passed to this method,
85 * please reference sati_translate_command().
87 * @return Indicate if the method was successfully completed.
88 * @retval SATI_SUCCESS This is returned in all other cases.
