9bbf9bfafb Clear the DFCNTRL register after every busfree.
When setting the HCNT registers, do so in ascending order.

When performing tagged queueing in non-paging mode, also check the
disconnected bit in the SCB as extra sanity during a reconection.

Make the labels in the DMA routine more sane.

When doing a DMA, if we see the DMADONE condition come true, we can
simply turn of the DMA enable bits in DFCNTRL without testing the FIFO
state as HDONE is true when DMADONE is true and this emplies the FIFO is
empty.

These changes clear up the data overrun error messages and seem to prevent
the "timed out in data-in phase" problems.

10f666af84 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

dfc97649f7 Clear the channel after (re)selection instead of once we see the bus go
free.

When we clear SCSIRATE, also clear the FAST20 bit in SXFRCTL0.  This also
allowed me to clean up some of the ULTRA code.

ULTRAENB->FAST20 to follow the convention in the Adaptec data books.

Fix the data-overrun code to set both stcnt and hcnt otherwise, the transfer
will just hang until we get a timeout.

Add implicit support for the NOOP message.  I've never heard of the driver
issueing a reject for one, but its silly to reject NOOP and who knows how a
device might react.

In the dma routine, check SDONE before cleaing SDMAEN.  The data books mention
SDONE possibly being cleared when SDMAEN is reset.  Clients of dma now need
to check if SINDEX is cleared to know if a phasemis occured.

Fix some comments to be correct.

9b86dcdae7 Add interface revision field to pci_register_lkm parameter list.pci.c pcibus.h
This parameter is intended to allow new kernels to work with old LKM binaries,
provided the revision ID is incremented whenever the PCI LKM interface is
changed. The revision ID does not at all protect against changes in data
structures accesses by the driver.

7ee6b3a702 In dma_finish, don't disturb the direction bit in DFCNTRL when turning off
host DMAs.  The additional test to ensure that the DMA has stopped is also
unnecessary since we've already waited for the DMA to complete.

ae22a22184 Fixed the SMC fifo bug fix. sioopen() hung while input was streaming in
with <= 100 usec between each character arrival time.  This didn't happen
until rev.1.75 of clock.c because DELAY(100) used to delay for closer to
80 usec than 100 usec, and the minimum time between character arrivals is
87.8 usec at the maximum supported speed of 115200 bps 8N1.

Clear DCD timestamp flag on close (the input timestamp flag is already
cleared).

637e1706b9 Fixes and workarounds for Hayes ESP:
- don't uselessly initialize the fifo "DMA" bit at attach time.
- initialize the fifo "DMA" bit at open time.  Without this, the device
  interrupts for every character received, reducing input performance
  to that of an 8250.
- don't uselessly initialize the fifo trigger level to 8 (scaled to
  256) at attach time.
- don't scale the fifo trigger level to 512 bytes.  The driver's pseudo-
  dma buffer has size 256, so it can't handle bursts of size 512 or 256.
  It should be able to handle the second lowest ftl (2 scaled to 64).
- don't reset the fifos in siostop().  Reset triggers a hardware bug
  involving wedging of the output interrupt bit  This workaround
  unfortunately requires ESP support to be configured.

a16faf06d2 Change the way DMA is handled during the command phase. Only test on
SDONE, not HDONE.

In the data phase dma handler, mask off just the enable bits instead of
clearing the whole register.  Clearing the direction bit could be bad.
Also don't stop a DMA until MREQPEND goes false.  Doing this may cause
an ABORT on the PCI bus although I have yet to see this happen.

Add definitions for MREQPEND and the BRDCTL register.  The BRDCTL register
is used to handle high byte termination and automatic termination testing.

e95f937a4f Clear the SCSI channel after we go to busfree instead of after re/selection.
Only enable reselections once the channel and SCSIRATE have been cleared.

Add a pause block around the test busy code in the non-tagged case to simplify
error recovery in the corner case of aborting an SCB that just got started.

Simplify reselection processing by removing the call to initialize_scsiid.

Clear the scsiseq re/select control bits and setup for catching bogus
busfrees earlier in the re/select process.

Improve the automatic PIO code.  It turns out that SPIORDY is not a reliable
hardware condition bit, so use REQINIT intstead.  Don't rely on PHASEMIS
either since it can take too long to come true.  Use a brute force comparison
instead.

Remove some unnecessary overhead in the command complete processing.  It
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition.  If we
don't see our interrupt in time, the system has bigger problems elsewhere.
If this ever does happen, the timeout handler will notice and retry the
command.

b293f5b41c Bruce pointed out a bogon:
cur_console is NULL when copy_font() is first called from scinit().  This
is apparently harmless when scinit() is called early from sccninit() -
page 0 is apparently mapped r/w then, and 0->status contains suitable
garbage.  However, when there is a serial console, scinit() is first
called from scattach() when the page tables are completely initialized,
so the NULL pointer causes a panic.
