Use the host message loop for any unknown message types instead of performing a reject message in the sequencer. Pass reject messages to the host message loop too which frees up a sequencer interrupt type slot. Default to issuing a bus reset if initiator mode is enabled. It seems that the reset scsi bus bit is not defined in the same location for all aic78xx BIOSes, so attempting to honor this setting will have to wait until I get more information on how to detect it. Nuke some unused variables.

* Serial EEPROM Control (p. 4-92 in 7870 Databook)
|
|
* Controls the reading and writing of an external serial 1-bit
|
|
* EEPROM Device. In order to access the serial EEPROM, you must
|
|
* first set the SEEMS bit that generates a request to the memory
|
|
* port for access to the serial EEPROM device. When the memory
|
|
* port is not busy servicing another request, it reconfigures
|
|
* to allow access to the serial EEPROM. When this happens, SEERDY
|
|
* gets set high to verify that the memory port access has been
|
|
* granted.
|
|
*
|
|
* After successful arbitration for the memory port, the SEECS bit of
|
|
* the SEECTL register is connected to the chip select. The SEECK,
|
|
* SEEDO, and SEEDI are connected to the clock, data out, and data in
|
|
* lines respectively. The SEERDY bit of SEECTL is useful in that it
|
|
* gives us an 800 nsec timer. After a write to the SEECTL register,
|
|
* the SEERDY goes high 800 nsec later. The one exception to this is
|
|
* when we first request access to the memory port. The SEERDY goes
|
|
* high to signify that access has been granted and, for this case, has
|
|
* no implied timing.
|
|
*
|

* See 93cx6.c for detailed information on the protocol necessary to
|

* on top of the BIOS values, so we re-use those for our per-target
|
|
* scratchspace (actually a value that can be copied directly into
|
|
* SCSIRATE). The kernel driver will enable synchronous negotiation
|
|
* for all targets that have a value other than 0 in the lower four

|
* bits of the target scratch space. This should work regardless of

* whether the bios has been installed.
