Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

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