Synchronize with other platforms:

	Strongly architect handles so we can more easily detect bogus
	handles. This switches us to a full 32 bits for all handles.

	Handle the case of FC disks disappearing and then reappearing-
	at least at the FC transport level.

	Some better and finer control of debug and non-debug printouts.

Add some more definitions appropriate for T10 standards
and use those cleaned up definitions.

Use 2100 style firmware loading if the load address and
load size is less than 64k. Some apparently buggy ROMs
out there choke otherwise.

Clean up some WWNN derivations from WWPN.

Checkpoint of some fairly major isp(4) rototilling.

Reintroduce more of a 'channel' concept in preparation for NP-IV support.
This gets rid of the chanA/chanB concept as the 2400 can have up to 128
virtual channels. Actually, with MID firmware you can also have the 2200
and 2300 support 'channels, but they do it with an FL-Port topology.
Because FC cards can now have 'channels', just about every support
function for fibre channel had to be redone to have a channel index
as well.  Rototill isp_ioctl.h for channel stuff as well.

Pick up a lot of work about fabric management (hopefully better) and keep
work in place that will allow for dynamic attachment/detachment of devices
(if I can figure out how to make the midlayer support it).

Merge the target code with external trees. Eventually it might even
be sorted out on NetBSD.

Update some firmware stuff.

Sync with head.

Major update to isp(4) driver to bring it in line with external sources.

The major changes are:

 + 4Gb (24XX) card support
 + Rewritten fabric and loop evaluation code
 + New f/w sets

The 4Gb changes required major rototilling, which caused a rewrite of
fabric and loop eval code. The latter can now be set up to tune for
dynamic device arrival/departure if the framework is set up for it,
or to be firm about waiting for devices.

Testing has been principally on amd64, i386 and sparc64 and seems to
not have broken things for me.

netbsd.org -> NetBSD.org

This was the last commit of this kind to src/sys, which is now totally
"NetBSD.org clean".  Thanks for the patiance, and sorry for all the commits.

Fix even stupider fix. It was, in fact, right the first time. Add
a comment clarifying things.

Fix egregious bug where we meant to use bit 5 (1<<5) instead of the
value of 5.

Catch up to -current

Add some A64 related support.

sync kqueue branch with HEAD

catch up with -current.

Further fix problems with 23XX ISR handling and correctly initialize the
23XX to use ZIO in preference to fast posting.

Catch up to -current.

Various changes to allow for overriding just loopid and/or iid.
Fix a random 23XX ISR reading bug. Be chattier about HBA_BOTCH
errors. More f/w cashdump layering.

catch up with -current on kqueue branch

Catch up with -current.

Fix seveeral issues- but the most important of which is that we have
to check if we get a RQCS_DATA_UNDERRUN - if we're an FC card, we may
not have RQCS_RU set- if it isn't set, we just lost a DATA XFR IU in the
middle of the exchange. In this case, we have to bomb out the whole xfer.
We had been getting silent data corruption before.

Catch up to -current.

Clean up a bit from the last checkin so that the correct result pointers
are used- didn't make a difference, but hey...

Put in commented out GFF_ID code- for use in future attempts to search
the fabric- this probably has to go thru the management server path.

Don't whine about handles we can't find if these are aborted commands
(we know we can't find the handles because we destroy handles after
a successful mailbox abort- we don't wait for the F/W to decide whether
it wants to return a status IOCB after this happens).

Redo fabric evaluation to not use GET ALL NEXT (GA_NXT). Switches seem
to be trying to wriggle out of supporting this well. Instead, use
GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the
port and node wwn. This should make working on fabrics a bit cleaner and
more stable.

This also caused some cleanup of SNS subcommand canonicalization so that
we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT,
print out the reason and explanation codes.

We'll keep the old GA_NXT method around if people want to uncomment a
controlling definition in ispvar.h.

This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument
and to have the caller explicitly say that a device is at the end of the
fabric list.

Catch up with -current.

Catch up to -current.

Implement F/W crashdumps for 2200 && 2300 cards (kernel compile option).

Distinguish between 2312 and 2300 cards (they *are* different). Enable
RIO (Reduced Interrupt Operation) for the LVD cards (hey- I've seen
batched completions of the 30 commands at a time with this,....)...

If we get a Port Logout on local loop topologies, we have to force the
f/w to log back in. The easiest way (for us) to do this is to force
a LIP. This also will wake up the disk that probably just had a f/w crash.

Implement mailbox 'continuations'- this allows interrupts to re-drive
a mailbox command if it's one that just essentially repeats the previous
mailbox command (e.g., f/w download). This saves a boatload of sleep/wakeup
twitches.

If we're not a 2300 and we're about to return with a 'bogus interrupt'- check
the semaphore register to be non-zero at all and outgoing mailbox 0- this
seems to be where some of the lost ISP1080 commands came from.

More catchup.

Sync kqueue branch with -current.

Catch up to -current.

Implement REDUCED INTERRUPT OPERATION usage for FC cards- this allows the
firmware to delay completion of commands so that it can attempt to batch
a bunch of completions at once- either returning 16 bit handles in mailbox
registers, or in a resposne queue entry that has a whole wad of 16 bit handles.

Distinguish between 2300 and 2312 chipsets- if only because the revisions
on the chips have different meanings.

Add more instrumentation plus ISP_GET_STATS and ISP_CLR_STATS ioctls.
Run up the maximum number of response queue entities we'll look at
per interrupt.

If we haven't set HBA role yet, always return success from isp_fc_runstate.

Major restructuring for swizzling to the request queue and unswizzling from
the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have
a complete set of inline functions in isp_inline.h. Each platform is
responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32}
macros.

The reason this needs to be done is that we need to have a single set of
functions that will work correctly on multiple architectures for both little
and big endian machines. It also needs to work correctly in the case that
we have the request or response queues in memory that has to be treated
specially (e.g., have ddi_dma_sync called on it for Solaris after we update
it or before we read from it).

One thing that falls out of this is that we no longer build requests in the
request queue itself. Instead, we build the request locally (e.g., on the
stack) and then as part of the swizzling operation, copy it to the request
queue entry we've allocated. I thought long and hard about whether this was
too expensive a change to make as it in a lot of cases requires an extra
copy. On balance, the flexbility is worth it. With any luck, the entry that
we build locally stays in a processor writeback cache (after all, it's only
64 bytes) so that the cost of actually flushing it to the memory area that is
the shared queue with the PCI device is not all that expensive. We may examine
this again and try to get clever in the future to try and avoid copies.

Another change that falls out of this is that MEMORYBARRIER should be taken
a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the
entry being added. But there had been many other places this had been missing.
It's now very important that it be done.

For NetBSD, it does a ddi_dmamap_sync as appropriate. This gets us out of
the explicit ddi_dmamap_sync on the whole response queue that we did for SBus
cards at each interrupt.

Set things up so that platforms that cannot have an SBus don't get a lot of
the SBus code checks (dead coded out).

Additional changes:

Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry,
the iptr value that gets returned is the value we intend to eventually plug
into the ISP registers as the entry *one past* the last one we've written-
*not* the current entry we're updating. All along we've been calling sync
functions on the wrong index value. Argh. The 'fix' here is to rename all
'iptr' variables as 'nxti' to remember that this is the 'next' pointer-
not the current pointer.

Devote a single bit to mboxbsy- and set aside bits for output mbox registers
that we need to pick up- we can have at least one command which does not
have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Explicitly decode GetAllNext SNS Response back *as* a GetAllNext response.
Otherwise, we won't unswizzle it correctly.

Nuke some additional __P macros.

Catch up with -current. Fix some bogons in the sparc64 kbd/ms
attach code. cd18xx conversion provided by mrg.

Fix various 2300 GB issues related to chip errata and documentation
misunderstandings. We also now can report our connection rate.

Catch up to -current.

Update the kqueue branch to HEAD.

Add support for 2 Gigabit cards (2300/2312). This necessitated a change
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).

Catch up with -current.

Add some wads more definitions. Add macros for request/response queue
in/out pointer access.

Sync with HEAD

Catch up with -current.

Add a few opcodes for target mode. Define firmware attributes (for FC f/w).

Pull up revisions 1.28-1.31 (requested by mjacob):
  Add structure defining FC-AL position maps. Add some 2X00 specific
  state flags for status response entries. Add the defines necessary
  for the REGISTER FC4 TYPE SNS subcommand. Change ICBOPT_USE_PORTNAME
  to ICBOPT_BOTH_WWNS.

Sync with HEAD.

Fix a longstanding bug- we had the sense of what bit 14
for the ICB firmware options meant- *I* had taken it to
mean that if you set it, Node Name would be ignored and
derived from Port Name. Actually, it meant the opposite.
As a consequence- change ICBOPT_USE_PORTNAME to the
define ICBOPT_BOTH_WWNS- makes more sense.

Add structure defining FC-AL position maps. The only tool that I know of
that really uses this is luxadm(8) under Solaris.

Sync with head (for UBC+NFS fixes, mostly).

Add some 2X00 specific state flags for status response entries. Add the
defines necessary for the REGISTER FC4 TYPE SNS subcommand.

Sync with HEAD

Fix pathnames in comment.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Complete rewrite of internals for isp core version 2.0.
Pullup to netbsd-1-5 approved by thorpej@netbsd.org.

Change _res field in ispstatusreq_t  to be req_response for FC.
Add some more FC specific response defines and split the response
defines into common, SCSI only and FC only cases.

Add a maintenance note

Core version 2.0 (platform version 1.0) rewrite of ISP driver. Some
interace cleanups, some new common functions. The major impact that
will be noticeable right away is that if you boot with not Fibre connected
to the FC cards, you no longer hang indefinitely.

add MBOX_GET_RESOURCE_COUNT command

Apply patch (requested by Matthew Jacob via he):
  Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies.
  Make sure we get a port database entry for the fabric name server.
  Preserve fabric logins if the device didn't change across fabric
  or port database changes, or the device has already logged into
  us (e.g., for target/initiator dual role devices like Veritas
  SANbox). Propagate class 3 service parameter changes where devices
  can change roles.

  Fix all occurrences of setting a sendmarker so that setting it
  for one bus on dual bus cards doesn't wipe a pending sendmarker
  for other busses on the same card.

  Comments added and clarifications made in some of the target mode code.

  Add support for > 12 byte CDBs.  Split out nvram reading into
  per-card functions.  Add proper Ultra2/Ultra3 support.  Upgrade
  firmware.

Update BA for new max_lun parameter for SCSIbusses. Clearify maximum luns
for FC HB based upon a SCCLUN define (15 for normal- 255 out of a possible
65535 for SCCLUN). Propagate loopid as adapter_target.

Roll minor platform version. Roll core version number.

Update mailbox definitions with cleaner target mode structure definitions.
Clean up some ENDIAN stuff. Correct botched ISP2100_NVRAM_HARDLOOPID offset.

pull up revs 1.6-1.9 from trunk (mjacob)

into same. Add a wad more definitions in this area.

fix headers

Some major thrashing to handle building for other than NetBSD.

There is one change of note- build a list of completing commands in
