While I'm there, handle better errors in trm_attach and remove the

as module. This also fix's issue kern/45713.
Fix - polling was implemented incorrectly for
adapter enquiry and adapter flush.
(2) Problem: PANIC when unloading driver
as module.
Fix - device nodes are not destroyed for amr0,
and amrd* when driver is unloaded
(3) Problem: PANIC from loading driver when
3ware adapter present, error message "Warning
"amrd is usurping twed's bmaj"
Fix - put #idef freebsd version < 500000 for
bmaj -1 -> amrd_cdevsw
(4) Problem: warnings in driver when compiling
with DAMR_DEBUG param enabled in Makefile
Fix - fix the warnings so driver can compile
when -Werror is present in Makefile.

This mostly consists of functionality to serialize accesses to
the two ATA channels (which can also be used to "fix" certain
PCI based controllers).
Add support for Acard controllers.
Enable the ATA driver in PC98 GENERIC, and add device hints.
Update man page with latest support.
The PC98 core team has kindly provided me with a PC98
machine that made this all possible, thanks to all that
contributed to that effort, without that this would
probably newer have been possible..

We allow the request to go through if it matches either a prefetchable
or a non-prefetchable part of the bridge. We do not check to make
sure it is the right kind of memory because most drivers to not yet
properly set RF_PREFETCHABLE (only cardbus seems to do so, and I'm not
entirely sure it does it right). RF_PREFETCHABLE was invented for
cardbus, so hasn't been properly documented yet.
This is still overridable by hw.pci.allow_unsupported_io_ranges, but
the need for that is greatly reduced, especially for the nvida driver.

version, plus add support for the new features found in the Rev B
version of the chip. The changelog is quite long and can be provided

HP -> CPQ
Rearrange IDs to better match which chips they use.
Convert to uniform product description strings.
Simplify 7901A setup function.
Add the NONPACKFIFO_BUG and PACED_NEGTABLE_BUG entries
for the A.
Add rev B bugs and features.
The double write workaround for CURRSCB is only required if
abort pending is set. Remove this work around and set the
abort pending bug bit on the B at least until we have better
confirmation that the double write is always safe.
Add updated H2B identifiers
Move IOCell paramters into softc and add a hook for the
OSM to modify these as well as other settings prior to
committing them to the chip.
SLEW -> SLEWRATE
PREQDIS in DEVCONFIG1 went away after the A2.
Remove all code that references this bit. This
is especially important since this bit was reused
in the B for a different HW fix workaround.
Properly set the AHD_NEW_IOCELL_OPTS and
AHD_NEW_DFCNTRL_OPTS features for the B.
Remove stray/random extra 7901A generic PCI
table entry. Also switch the correct 7901A
generic entry to use ID_ALL_MASK since we
can only differentiate the 7901A from the
7902 by checking for a "type field" of 0xE.
Set AHD_INTCOLLISIONT_BUG for the Rev B.
Set the PREQDIS bit in DEVCONFIG1 for the B. The
bit is misnamed, but seems to disable a work-around
that breaks on the B on PCI busses.
Add a routine for testing memory mapped register access.
This will hopefully detect things like buggy via chipsets
so that the OSM can fallback to using I/O mapped access
when memory mapped I/O simply will not work.

diagnostic "Setting Mode" messages.

aic7xxx.c:
aic7xxx.h:
aic7xxx.reg:
aic7xxx.seq:
Bring in the protocol violation handler from the U320
driver and replace the NO_IDENT sequencer interrupt code
with the PROTO_VIOLATION code. Support for this code
required the following changes:
SEQ_FLAGS:
IDENTIFY_SEEN -> NOT_IDENTIFIED
Added NO_CDB_SENT
SCB_CONTROL:
TARGET_SCB == STATUS_RCVD for initiator mode
scb->flags:
Added SCB_TARGET_SCB since we cannot rely on
TARGET_SCB as a target/initiator differentiator
due to it being overloaded in initiator mode to
indicate that status has been received.
aic7xxx.seq:
Move data fifo CLRCHN to mesgin_rdptrs which is a safer
location for doing this operation. This also saves a
sequencer instruction.
aic7xxx.c:
aic7xxx.h:
Change ahc/ahd_upate_neg_request() to take a "negotiation
type" enum that allows us to negotiate:
o only if the goal and current parameters differ.
o only if the goal is non-async
o always - even if the negotiation will be for async.
aic7xxx.seq:
Reset the FIFO whenever a short CDB transfer occurs
so that the FIFO contents do not corrupt a future CDB
transfer retry.
Add support for catching the various protocol violations
handled by ahc_handle_protocol_violation.
Reformat some comments.
aic7xxx.c:
aic7xxx.h:
Just for safety, have the aic7xxx driver probe
the stack depth.
aic7xxx.c:
aic7xxx.h:
Save and restore stack contents during diagnostics.
Some chip variants overwrite stale entries on a
stack "pop".
Don't use 0 to probe the stack depth. 0 is the typical
value used to backfill the stack if entries are overwritten
on a "pop".
aic7xxx.h:
Add a missing typedef.
Collapse SCB flag entries so they are bit contiguous.
Add AHD_ULTRA2_XFER_PERIOD for narrow fallback calculations
aic7xxx.c:
Don't panic (as a diagnostic to catch bugs) if we decided to
force the renegotiation of async even if we believe we are
already async. This should allow us to negotiate async instead
of the full user goal rate during startup if bus resets are
disabled.
Add a space to the end of the ahc/ahd_print_devinfo routines
so that it behaves as expected by the code that uses it.
Only force a renegotiation on a selection timeout
if the SCB was valid. Doing otherwise may be dangerous
as the connection was not valid for an unknown reason.
Add additional diagnostic output to ahc_dump_card_state(),
and have it use the register pretty printing functions.
Update ahc_reg_print() to handle a NULL cur_col.
Add a newline to ahc_dump_card_state() output.
Bring back "use_ppr". We need to use_ppr anytime
doppr is true or we have non-zero protocol options.
The later case was not handled in the recent removal
of use_ppr.
Move a comment and remove a useless clearing of use_ppr.
Don't disable ENBUSFREE when single stepping on
a DT capable controller. We cannot re-enable unexpected
busfree detection, so we must clear BUSFREE on each
step instead.
Correct the lookup of the SCB ID in ahc_handle_proto_error.
Remove a diagnostic printf.
Remove unecessary restoration of the STACK for older
chips.
