ad0ab75379 Prepare for FC-Tape support. This involved doing a lot of little cleanups
and crosschecks against firmware documentation. We now check and report
FC firmware attributes and at least are now prepared for the upper 48 bits
of f/w attributes (which are probably for the 8100 or later cards). This
involed changing how inbits and outbits are calculated for varios commands,
hopefully clearer and cleaner. This also caused me to clean up the actual
mailbox register usage. Finally, we are now unconditionally using a CRN
for initiator mode.

A longstanding issue with the 2400/2500 is that they do *not* support
a "Prefer PTP followed by loop", which explains why enabling that
caused the f/w to crash.

A slightly more invasive change is to let the firmware load entirely
drive whether multi_id support is enabled or not.

443e752d97 Revamp the pieces of some of the stuff I forgot to do when shifting to
32 bit handles. The RIO (reduced interrupt operation) and fast posting
for the parallel SCSI cards were all 16 bit handles. Furthermore,
target mode parallel SCSI only can have 16 bit handles.

Use part of a supplied patch to switch over to using 32 bit handles.
Be a bit more conservative here and only do this for parallel SCSI
for the 12160 (Ultra3) cards. There were a lot of marginal Ultra2
cards, and, frankly, few are findable now for testing.

Fix the target handle routine to only do 16 bit handles for parallel
SCSI cards. This is okay because the upper sixteen bits of the new
32 bit handles is a sequence number to help protect against duplicate
completions. This would be very unlikely to happen with parallel
SCSI target mode, and wasn't present before, so we're no worse off
than we used to be.

While we're at it, finally split the async mailbox completion handlers
into FC and parallel SCSI functions. This makes it much cleaner and
easier to figure out what is or isn't a legal async mailbox completion
code for different card classes.

2df76c160b Add 8Gb support (isp_2500). Fix a fair number of configuration and
firmware loading bugs.

Target mode support has received some serious attention to make it
more usable and stable.

Some backward compatible additions to CAM have been made that make
target mode async events easier to deal with have also been put
into place.

Further refinement and better support for NP-IV (N-port Virtualization)
is now in place.

Code for release prior to RELENG_7 has been stripped away for code clarity.

af4394d40a Don't attempt to load illegal hard loop addresses into
an ICB. This shows up on card restarts, and usually for
2200-2300 cards. What happens is that we start up,
attempting to acquire a hard address. We end up instead
being an F-port topology, which reports out a loop id
of 0xff (or 0xffff for 2K Login f/w). Then, if we restart,
we end up telling the card to go off an acquire this loop
address, which the card then rejects. Bah.

Compilation fixes from Solaris port.

8a97c03a7a Do various fixes to support firmware loading for the 2322
(and by extension, the 2422).

One peculiar thing I've found with the 2322 is that if you
don't force it to do Hard LoopID acquisition, the firmware
crashes. This took a while to figure out.

While we're at it, fix various bugs having to do with NVRAM
reading and option setting with respect to pieces of NVRAM.

1dae40eb49 a) clean up some declaration stuff (i.e., make more modern with respect
to getting rid u_int for uint and so on).

b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two
DMA callback functions- one when we have bus_addr_t > 4 bits in width and
the other which should be normal. Even Cheezier in that we turn off setting
up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work
on this in a week or so.

c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient
memory to really test > 4GB). LINT check under amd64.

e526523707 First of several commits as this driver is dusted off and maybe brought
up to date.  Principle changes for this reelase is to support 2K Port Login
firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only
come with the 2K Port Login firmware. The 2322 should now work- but we don't
have firmware sets for it in ispfw (as the change to load 2K Port Login f/w
hasn't been made- that f/w is so big it has to be loaded in more than one
chunk).

Other changes are the beginnings of cleaning up some long standing target
mode issues. The next changes here will incorporate a lot of bug fixes
from others.

Finally, some copyright cleanup and attempts to make the parts of the
driver that are FreeBSD specific start conforming more to FreeBSD style.

b894188248 Support for f/w crash dumps (2200 && 23XX).
If you want QLogic to look at a potential f/w problem for FC cards, you really
have to provide them info in the format they expect. This involves dumping
a lot of hardware registers (> 300 16 bit registers) and a lot of SRAM
(> 128KB minimum). Thus all of this code is #ifdef protected which will
become an option so that the memory allocation of where to dump the crash
image is pretty expensive. It's worth it if you have a reproducible problem
because they have some tools that can tell them, given the f/w version,
the precise state of everything.

75c1e828c0 + A variety of 23XX changes:
disable MWI on 2300

	based on function code, set an 'isp_port' for the 2312- it's a
	separate instance, but the NVRAM is shared, and the second port's
	NVRAM is at offset 256.

+ Enable RIO operation for LVD SCSI cards. This makes a *big* difference
as even under reasonable load we get batched completions of about 30
commands at a time on, say, an ISP1080.

+ Do 'continuation' mailbox commands- this allows us to specify a work
area within the softc and 'continue' repeated mailbox commands. This is
more or less on an ad hoc basis and is currently only used for firmware
loading (which f/w now loads substantially faster becuase the calling
thread is only woken when all the f/w words are loaded- not for each
one of the 40000 f/w words that gets loaded).

+ If we're about to return from isp_intr with a 'bogus interrupt' indication,
and we're not a 23XX card, check to see whether the semaphore register is
currently *2* (not *1* as it should be) and whether there's an async completion
sitting in outgoing mailbox0. This seems to capture cases of lost fast posting
and RIO interrupts that the 12160 && 1080 have been known to pump out under
extreme load (extreme, as in > 250 active commands).

+ FC_SCRATCH_ACQUIRE/FC_SCRATCH_RELEASE macros.

+ Endian correct swizzle/unswizzle of an ATIO2 that has a WWPN in it.

126ec86486 Add 2 Gigabit Fibre Channel support (2300 && 2312 cards). This required
some reworking (and consequent cleanup) of the interrupt service code.

Also begin to start a cleanup of target mode support that will (eventually)
not require more inforamtion routed with the ATIO to come back with the
CTIO other than tag.

distinct from resource starvation for simq freeze/unfreeze actions).
