324 * Fujitsu MB86965 JLI mode probe routines.
326 * 86965 has a special operating mode called JLI (mode 0), under which
327 * the chip interfaces with ISA bus with a software-programmable
328 * configuration. (The Fujitsu document calls the feature "Plug and
329 * play," but it is not compatible with the ISA-PnP spec. designed by
330 * Intel and Microsoft.) Ethernet cards designed to use JLI are
331 * almost same, but there are two things which require board-specific
332 * probe routines: EEPROM layout and IRQ pin connection.
334 * JLI provides a handy way to access EEPROM which should contains the
335 * chip configuration information (such as I/O port address) as well
336 * as Ethernet station (MAC) address. The chip configuration info. is
337 * stored on a fixed location. However, the station address can be
338 * located anywhere in the EEPROM; it is up to the board designer to
339 * determine the location. (The manual just says "somewhere in the
340 * EEPROM.") The fe driver must somehow find out the correct
343 * Another problem resides in the IRQ pin connection. JLI provides a
344 * user to choose an IRQ from up to four predefined IRQs. The 86965
345 * chip has a register to select one out of the four possibilities.
346 * However, the selection is against the four IRQ pins on the chip.
347 * (So-called IRQ-A, -B, -C and -D.) It is (again) up to the board
348 * designer to determine which pin to connect which IRQ line on the
349 * ISA bus. We need a vendor (or model, for some vendor) specific IRQ
352 * The routine fe_probe_jli() provides all probe and initialization
353 * processes which are common to all JLI implementation, and sub-probe
354 * routines supply board-specific actions.
356 * JLI sub-probe routine has the following template:
358 * u_short const * func (struct fe_softc * sc, u_char const * eeprom);
360 * where eeprom is a pointer to an array of 32 byte data read from the
361 * config EEPROM on the board. It retuns an IRQ mapping table for the
362 * board, when the corresponding implementation is detected. It
363 * returns a NULL otherwise.
365 * Primary purpose of the functin is to analize the config EEPROM,
366 * determine if it matches with the pattern of that of supported card,
367 * and extract necessary information from it. One of the information
368 * expected to be extracted from EEPROM is the Ethernet station (MAC)
369 * address, which must be set to the softc table of the interface by
370 * the board-specific routine.
