319 * Fujitsu MB86965 JLI mode probe routines.
320 *
321 * 86965 has a special operating mode called JLI (mode 0), under which
322 * the chip interfaces with ISA bus with a software-programmable
323 * configuration. (The Fujitsu document calls the feature "Plug and
324 * play," but it is not compatible with the ISA-PnP spec. designed by
325 * Intel and Microsoft.) Ethernet cards designed to use JLI are
326 * almost same, but there are two things which require board-specific
327 * probe routines: EEPROM layout and IRQ pin connection.
328 *
329 * JLI provides a handy way to access EEPROM which should contains the
330 * chip configuration information (such as I/O port address) as well
331 * as Ethernet station (MAC) address. The chip configuration info. is
332 * stored on a fixed location. However, the station address can be
333 * located anywhere in the EEPROM; it is up to the board designer to
334 * determine the location. (The manual just says "somewhere in the
335 * EEPROM.") The fe driver must somehow find out the correct
336 * location.
337 *
338 * Another problem resides in the IRQ pin connection. JLI provides a
339 * user to choose an IRQ from up to four predefined IRQs. The 86965
340 * chip has a register to select one out of the four possibilities.
341 * However, the selection is against the four IRQ pins on the chip.
342 * (So-called IRQ-A, -B, -C and -D.) It is (again) up to the board
343 * designer to determine which pin to connect which IRQ line on the
344 * ISA bus. We need a vendor (or model, for some vendor) specific IRQ
345 * mapping table.
346 *
347 * The routine fe_probe_jli() provides all probe and initialization
348 * processes which are common to all JLI implementation, and sub-probe
349 * routines supply board-specific actions.
350 *
351 * JLI sub-probe routine has the following template:
352 *
353 * u_short const * func (struct fe_softc * sc, u_char const * eeprom);
354 *
355 * where eeprom is a pointer to an array of 32 byte data read from the
356 * config EEPROM on the board. It retuns an IRQ mapping table for the
357 * board, when the corresponding implementation is detected. It
358 * returns a NULL otherwise.
359 *
360 * Primary purpose of the functin is to analize the config EEPROM,
361 * determine if it matches with the pattern of that of supported card,
362 * and extract necessary information from it. One of the information
363 * expected to be extracted from EEPROM is the Ethernet station (MAC)
364 * address, which must be set to the softc table of the interface by
365 * the board-specific routine.

319 * Fujitsu MB86965 JLI mode probe routines.
320 *
321 * 86965 has a special operating mode called JLI (mode 0), under which
322 * the chip interfaces with ISA bus with a software-programmable
323 * configuration. (The Fujitsu document calls the feature "Plug and
324 * play," but it is not compatible with the ISA-PnP spec. designed by
325 * Intel and Microsoft.) Ethernet cards designed to use JLI are
326 * almost same, but there are two things which require board-specific
327 * probe routines: EEPROM layout and IRQ pin connection.
328 *
329 * JLI provides a handy way to access EEPROM which should contains the
330 * chip configuration information (such as I/O port address) as well
331 * as Ethernet station (MAC) address. The chip configuration info. is
332 * stored on a fixed location. However, the station address can be
333 * located anywhere in the EEPROM; it is up to the board designer to
334 * determine the location. (The manual just says "somewhere in the
335 * EEPROM.") The fe driver must somehow find out the correct
336 * location.
337 *
338 * Another problem resides in the IRQ pin connection. JLI provides a
339 * user to choose an IRQ from up to four predefined IRQs. The 86965
340 * chip has a register to select one out of the four possibilities.
341 * However, the selection is against the four IRQ pins on the chip.
342 * (So-called IRQ-A, -B, -C and -D.) It is (again) up to the board
343 * designer to determine which pin to connect which IRQ line on the
344 * ISA bus. We need a vendor (or model, for some vendor) specific IRQ
345 * mapping table.
346 *
347 * The routine fe_probe_jli() provides all probe and initialization
348 * processes which are common to all JLI implementation, and sub-probe
349 * routines supply board-specific actions.
350 *
351 * JLI sub-probe routine has the following template:
352 *
353 * u_short const * func (struct fe_softc * sc, u_char const * eeprom);
354 *
355 * where eeprom is a pointer to an array of 32 byte data read from the
356 * config EEPROM on the board. It retuns an IRQ mapping table for the
357 * board, when the corresponding implementation is detected. It
358 * returns a NULL otherwise.
359 *
360 * Primary purpose of the functin is to analize the config EEPROM,
361 * determine if it matches with the pattern of that of supported card,
362 * and extract necessary information from it. One of the information
363 * expected to be extracted from EEPROM is the Ethernet station (MAC)
364 * address, which must be set to the softc table of the interface by
365 * the board-specific routine.
