fca7fce17e Deal with targets > 7 on wide Buslogic controllers. Remember the "wide"
bit from the extended setup inquiry and key off it to:
- Force synchronous negotiation on targs > 7.
- Read additional information returned by wide cards on inquire setup.
- Read sync period on targs > 7.
- Display sync period/offset on targs > 7.
- Set scsi_link.max_target to 15.

e7a52ac635 Add missing fields to the extended_inquire reply struct.
Fixes probing of aha154x's, and provides wide/ultra bits for the MI scsi code.

79b026a8f3 * Add command struct and modifier definitions for controlling the
ISA-compatible port space of PCI buslogic cards.

* Add call to bha_pci.c to disable the ISA-compatible ports of a PCI
  device.  The ISA-compatible ports are enabled by default, which
  causes the card to be autoconfigured a second time as an ISA device,
  which appears to deadlock the card.

* Change bha_cmd() to return the number of bytes it actually received
  in response to a command, or -1 on error.

*  Use heuristics (checking for bha-only registers, and checking the size
   of the response to BHA_INQURE_EXTENDED) to bha_find, to make sure the
   bha driver never matches an aha (Adaptec    1542 or compatible) device.

A single kernel should now boot on either Adaptec or BusLogic controllers,
provided we always probe for BusLogic devices before Adaptec devices,
but this has not yet been verified.

06fdef11fd Split the BusLogic driver apart, and rename it to `bha (like BSDi). 1996-08-31 20:18:24 +00:00
