aic7770.c:

aic7xxx_pci.c:
	Enable board generation of interrupts only once our handler is
	in place and all other setup has occurred.

aic7xxx.c:
	More conversion of data types to ahc_* names.  tmode_tstate and
	tmode_lstate are the latest victims.

	Clean up the check condition path by branching early rather
	than indenting a giant block of code.

	Add support for target mode initiated sync negotiation.
	The code has been tested by forcing the feature on for
	all devices, but for the moment is left inaccesible until
	a decent mechanism for controlling the behavior is complete.
	Implementing this feature required the removal of the
	old "target message request" mechanism.  The old method
	required setting one of the 16 bit fields to initiate
	negotiation with a particular target.  This had the nice
	effect of being easy to change the request and have it
	effect the next command.  We now set the MK_MESSAGE bit
	on any new command when negotiation is required.  When
	the negotiation is successful, we walk through and clean
	up the bit on any pending commands.  Since we have to walk
	the commands to reset the SCSI syncrate values so no additional
	work is required.  The only drawback of this approach is that
	the negotiation is deferred until the next command is queued to
	the controller.  On the plus side, we regain two bytes of
	sequencer scratch ram and 6 sequencer instructions.

	When cleaning up a target mode instance, never remove the
	"master" target mode state object.  The master contains
	all of the saved SEEPROM settings that control things like
	transfer negotiations.  This data will be cloned as the
	defaults if a target mode instance is re-instantiated.

	Correct a bug in ahc_set_width().  We neglected to update
	the pending scbs to reflect the new parameters.  Since
	wide negotiation is almost always followed by sync
	negotiation it is doubtful that this had any real
	effect.

	When in the target role, don't complain about
	"Target Initiated" negotiation requests when an initiator
	negotiates with us.

	Defer enabling board interrupts until after ahc_intr_enable()
	is called.

	Pull all info that used to be in ahc_timeout for the FreeBSD
	OSM into ahc_dump_card_state().  This info should be printed
	out on all platforms.

aic7xxx.h:
	Add the SCB_AUTO_NEGOITATE scb flag.  This allows us to
	discern the reason the MK_MESSAGE flag is set in the hscb
	control byte.  We only want to clear MK_MESSAGE in
	ahc_update_pending_scbs() if the MK_MESSAGE was set due
	to an auto transfer negotiation.

	Add the auto_negotiate bitfield for each tstate so that
	behavior can be controlled for each of our enabled SCSI
	IDs.

	Use a bus interrupt handler vector in our softc rather
	than hard coding the PCI interrupt handler.  This makes
	it easier to build the different bus attachments to
	the aic7xxx driver as modules.

aic7xxx.reg:
	Remove the TARGET_MSG_REQUEST definition for sequencer ram.

aic7xxx.seq:
	Fix a few target mode bugs:

		o If MK_MESSAGE is set in an SCB, transition to
		  message in phase and notify the kernel so that
		  message delivery can occur.  This is currently
		  only used for target mode initiated transfer
		  negotiation.

		o Allow a continue target I/O to compile without
		  executing a status phase or disconnecting.  If
		  we have not been granted the disconnect privledge
		  but this transfer is larger than MAXPHYS, it may
		  take several CTIOs to get the job done.

	Remove the tests of the TARGET_MSG_REQUEST field in scratch ram.

aic7xxx_freebsd.c:
	Add support for CTIOs that don't disconnect.  We now defer
	the clearing of our pending target state until we see a
	CTIO for that device that has completed sucessfully.

	Be sure to return early if we are in a target only role
	and see an initiator only CCB type in our action routine.

	If a CTIO has the CAM_DIS_DISCONNECT flag set, propogate
	this flag to the SCB.  This flag has no effect if we've
	been asked to deliver status as well.  We will complete
	the command and release the bus in that case.

	Handle the new auto_negotiate field in the tstate correctly.

	Make sure that SCBs for "immediate" (i.e. to continue a non
	disconnected transaction) CTIO requests get a proper mapping
	in the SCB lookup table.  Without this, we'll complain when
	the transaction completes.

	Update ahc_timeout() to reflect the changes to ahc_dump_card_state().

aic7xxx_inline.h:
	Use ahc->bus_intr rather than ahc_pci_intr.
