        Fix a jump in our unexpected non-packetized phase
        handler to use an explicit lable.  The old code
        had a hardcoded jump offset that was off by one
        instruction.

Apply the following change made on 5/26/2003 21:26:51 by gibbs to the
FreeBSD ahd driver:

Correct/Simplify ignore wide residue message handling

aic79xx.c:
	In ahd_handle_ign_wide_residue():
	o Use SCB_XFERLEN_ODD SCB field to determine transfer
	  "oddness" rather than the DATA_COUNT_ODD logic.
	  SCB_XFERLEN_ODD is toggled on every ignore wide
	  residue message so that multiple ignore wide residue
	  messages for the same transaction are properly supported.
	o If the sg list has been exausted, the sequencer
	  doesn't bother to update the residual data count
	  since it is known to be zero.  Perform the zeroing
	  manually before calculating the remaining data count.
	o Use multibyte in/out macros instead of shifting/masking
	  by hand.

aic79xx_inline.h:
	In ahd_setup_scb_common(), setup the SCB_XFERLEN_ODD field.

aic79xx.reg:
	Use the SCB_TASK_ATTRIBUTE field as a bit field in the
	non-packetized case.  We currently only define one bit,
	SCB_XFERLEN_ODD.

	Remove the ODD_SEG bit field that was used to carry the odd
	transfer length information through the SG cache.  This
	is obviated by SCB_XFERLEN_ODD field.

	Remove the DATA_COUNT_ODD scratch ram byte that was used
	dynamicaly compute data transfer oddness.  This is obviated
	by SCB_XFERLEN_ODD field.

aic79xx.seq:
	Remove all updates to the DATA_COUNT_ODD scratch ram field.
	Remove all uses of ODD_SEG.  These two save quite a few
	sequencer instructions.

	Use SCB_XFERLEN_ODD to validate the end of transfer
	ignore wide residue message case.

Apply the following change made 5/26/2003 21:18:48 by gibbs to the
FreeBSD ahd driver:

Change hadling of the Rev. A packetized lun output bug
to be more efficient by having the sequencer copy the
single byte of valid lun data into the long lun field.

aic79xx.c:
	Memset our hardware SCB to 0 so that untouched
	fields don't confuse diagnostic output.  With the
	old method for handling the Rev A bug, if the long
	lun field was not 0, this could result in bogus
	lun information being sent to drives.

	Use the same SCB transfer size for all chip types
	now that the long lun is not DMA'ed to the chip.

aic79xx.seq:
	Add code to copy lun information for Rev.A hardware.

aic79xx_inline.h:
	Remove host update of the long_lun field on every
	packetized command.

instead of having the kernel proccess these failures via
the completion queue.  This is done because:

 o The old scheme required us to pause the sequencer and clear
   critical sections for each SCB.  It seems that these pause
   actions, if coincident with a sequencer FIFO interrupt, would
   result in a FIFO interrupt getting lost or directing to the
   wrong FIFO.  This caused hangs when the driver was stressed
   under high "queue full" loads.
 o The completion code assumed that it was always called with
   the sequencer running.  This may not be the case in timeout
   processing where completions occur manually via
   ahd_pause_and_flushwork().
 o With this scheme, the extra expense of clearing critical
   sections is avoided since the sequencer will only self pause
   once all pending selections have cleared and it is not in
   a critical section.

  aic79xx.c
        Add code to handle the new BAD_SCB_STATUS sequencer
        interrupt code.  This just redirects the SCB through
        the already existing ahd_complete_scb() code path.
        Remove code in ahd_handle_scsi_status() that paused
        the sequencer, made sure that no selections where
        pending, and cleared critical sections.  Bad
        status SCBs are now only processed when all of these
        conditions are true.

  aic79xx.reg:
        Add the BAD_SCB_STATUS sequencer interrupt code.

  aic79xx.seq:
        When completing an SCB upload to the host, if
        we are doing this because the SCB contains non-zero
        SCSI status, defer completing the SCB until there
        are no pending selection events.  When completing
        these SCBs, use the new BAD_SCB_STATUS sequencer
        interrupt.  For all other uploaded SCBs (currently
        only for underruns), the SCB is completed via the
        normal done queue.  Additionally, keep the SCB that
        is currently being uploaded on the COMPLETE_DMA_SCB
        list until the dma is completed, not just until the
        DMA is started.  This ensures that the DMA is restarted
        properly should the host disable the DMA transfer for
        some reason.

        In our RevA workaround for Maxtor drives, guard against
        the host pausing us while trying to pause I/O until the
        first data-valid REQ by clearing the current snapshot
        so that we can tell if the transfer has completed prior
        to us noticing the REQINIT status.

        In cfg4data_intr, shave off an instruction before getting
        the data path running by adding an entrypoint to the
        overrun handler to also increment the FIFO use count.

        In the overrun handler, be sure to clear our LONGJMP
        address in both exit paths.

Perform a few sequencer optimizations.

  aic79xx.c:
        Print the full path from the SCB when a packetized
        status overrun occurs.

        Remove references to LONGJMP_SCB which is being
        removed from firmware usage.

        Print the new SCB_FIFO_USE_COUNT field in the
        per-SCB section of ahd_dump_card_state().  The
        SCB_TAG field is now re-used by the sequencer,
        so it no longer makes sense to reference this
        field in the kernel driver.

  aic79xx.h:
        Re-arrange fields in the hardware SCB from largest
        size type to smallest.  This makes it easier to
        move fields without changing field alignment.

        The hardware scb tag field is now down near the
        "spare" portion of the SCB to facilitate reuse
        by the sequencer.

  aic79xx.reg:
        Remove LONGJMP_ADDR.

        Rearrange SCB fields to match aic79xx.h.
        Add SCB_FIFO_USE_COUNT as the first byte
        of the SCB_TAG field.

  aic79xx.seq:
        Add a per-SCB "Fifos in use count" field and use
        it to determine when it is safe (all data posted)
        to deliver status back to the host.  The old method
        involved polling one or both FIFOs to verify that
        the current task did not have pending data.  This
        makes running down the GSFIFO very cheap, so we
        will empty the GSFIFO in one idle loop pass in
        all cases.

        Use this simplification of the completion process
        to prune down the data FIFO teardown sequencer for
        packetized transfers.  Much more code is now shared
        between the data residual and transfer complete cases.

        Correct some issues in the packetized status handler.
        It used to be possible to CLRCHN our FIFO before status
        had fully transferred to the host.  We also failed to
        handle NONPACKREQ phases that could occur should a CRC
        error occur during transmission of the status data packet.

Correct a few big endian issues:

  aic79xx.c:
  aic79xx_inline.h:
  aic79xx_pci.c:
  aic79xx_osm.c:
        o Always get the SCB's tag via the SCB_GET_TAG acccessor
        o Add missing use of byte swapping macros when touching
          hscb fields.
        o Don't double swap SEEPROM data when it is printed.
          Correct a big-endian bug.  We cannot assign a
        o When assigning a 32bit LE variable to a 64bit LE
          variable, we must be explict about how the words
          of the 64bit LE variable are initialized.  Cast to
          (uint32_t*) to do this.

aic79xx.c:
        In ahd_clear_critical_section(), hit CRLSCSIINT
        after restoring the interrupt masks to avoid what
        appears to be a glitch on SCSIINT.  Any real SCSIINT
        status will be persistent and will immidiately
        reset SCSIINT.  This clear should only get rid of
        spurious SCSIINTs.

        This glitch was the cause of the "Unexpected PKT busfree"
        status that occurred under high queue full loads

        Call ahd_fini_scbdata() after shutdown so that
        any ahd_chip_init() routine that might access
        SCB data will not access free'd memory.

        Reset the bus on an IOERR since the chip doesn't
        seem to reset to the new voltage level without
        this.
        Change offset calculation for scatter gather maps
        so that the calculation is correct if an integral
        multiple of sg lists does not fit in the allocation
        size.

        Adjust bus dma tag for data buffers based on 39BIT
        addressing flag in our softc.

        Use the QFREEZE count to simplify ahd_pause_and_flushworkd().
        We can thus rely on the sequencer eventually clearing ENSELO.

        In ahd_abort_scbs(), fix a bug that could potentially
        corrupt sequencer state.  The saved SCB was being
        restored in the SCSI mode instead of the saved mode.
        It turns out that the SCB did not need to be saved at all
        as the scbptr is already restored by all subroutines
        called during this function that modify that register.

aic79xx.c:
aic79xx.h:
aic79xx_pci.c:
        Add support for parsing the seeprom vital product
        data.  The VPD data are currently unused.

aic79xx.h:
aic79xx.seq:
aic79xx_pci.c:
        Add a firmware workaround to make the LED blink
        brighter during packetized operations on the H2A.

aic79xx_inline.h:
        The host does not use timer interrupts, so don't
        gate our decision on whether or not to unpause
        the sequencer on whether or not a timer interrupt
        is pending.
