With this, I can build various ports on a 10.0-CURRENT system without
hacking or hiding the version number.
This commit should be reverted when there is a cleaner fix in autotools
and/or ports/Mk/bsd.port.mk.
The original patch is from Ed Schouten but needed some additions.

o Remove redundant lookups of base address in cf_identify
o Fix some indenting issues
o Fix an identification bug that uses DRQ to checlk for ident block

Add some improvements in the idle table callbacks:
- Replace instances of manual assembly instruction "hlt" call
with halt() function calling.
- In cpu_idle_mwait() avoid races in check to sched_runnable() using
the same pattern used in cpu_idle_hlt() with the 'hlt' instruction.
- Add comments explaining the logic behind the pattern used in
cpu_idle_hlt() and other idle callbacks.
Pre-11n devices and AR5416 use AR_PHY(263) for current RX RSSI.
AR9130 and later have a fourth calibration register (for doing
ADC calibration) and thus the register has moved to AR_PHY(271).
This isn't currently used by any of the active code; I'm committing
this for completeness and in case any third party code attempts to
use it for legacy reasons.
It is reported that on some chips (e.g. the 970MP) behavior of POW bit set
simultaneously with modifying other bits is undefined and may cause hangs.
The race should be handled in some other way, but for now just get back.

CAM.
Desriptor sense is a new sense data format that originated in SPC-3. Among
other things, it allows for an 8-byte info field, which is necessary to
pass back block numbers larger than 4 bytes.
This change adds a number of new functions to scsi_all.c (and therefore
libcam) that abstract out most access to sense data.
This includes a bump of CAM_VERSION, because the CCB ABI has changed.
Userland programs that use the CAM pass(4) driver will need to be
recompiled.
camcontrol.c: Change uses of scsi_extract_sense() to use
scsi_extract_sense_len().
Use scsi_get_sks() instead of accessing sense key specific
data directly.
scsi_modes: Update the control mode page to the latest version (SPC-4).
scsi_cmds.c,
scsi_target.c: Change references to struct scsi_sense_data to struct
scsi_sense_data_fixed. This should be changed to allow the
user to specify fixed or descriptor sense, and then use
scsi_set_sense_data() to build the sense data.
ps3cdrom.c: Use scsi_set_sense_data() instead of setting sense data
manually.
cam_periph.c: Use scsi_extract_sense_len() instead of using
scsi_extract_sense() or accessing sense data directly.
cam_ccb.h: Bump the CAM_VERSION from 0x15 to 0x16. The change of
struct scsi_sense_data from 32 to 252 bytes changes the
size of struct ccb_scsiio, but not the size of union ccb.
So the version must be bumped to prevent structure
mis-matches.
scsi_all.h: Lots of updated SCSI sense data and other structures.
Add function prototypes for the new sense data functions.
Take out the inline implementation of scsi_extract_sense().
It is now too large to put in a header file.
Add macros to calculate whether fields are present and
filled in fixed and descriptor sense data
scsi_all.c: In scsi_op_desc(), allow the user to pass in NULL inquiry
data, and we'll assume a direct access device in that case.
Changed the SCSI RESERVED sense key name and description
to COMPLETED, as it is now defined in the spec.
Change the error recovery action for a number of read errors
to prevent lots of retries when the drive has said that the
block isn't accessible. This speeds up reconstruction of
the block by any RAID software running on top of the drive
(e.g. ZFS).
In scsi_sense_desc(), allow for invalid sense key numbers.
This allows calling this routine without checking the input
values first.
Change scsi_error_action() to use scsi_extract_sense_len(),
and handle things when invalid asc/ascq values are
encountered.
Add a new routine, scsi_desc_iterate(), that will call the
supplied function for every descriptor in descriptor format
sense data.
Add scsi_set_sense_data(), and scsi_set_sense_data_va(),
which build descriptor and fixed format sense data. They
currently default to fixed format sense data.
Add a number of scsi_get_*() functions, which get different
types of sense data fields from either fixed or descriptor
format sense data, if the data is present.
Add a number of scsi_*_sbuf() functions, which print
formatted versions of various sense data fields. These
functions work for either fixed or descriptor sense.
Add a number of scsi_sense_*_sbuf() functions, which have a
standard calling interface and print the indicated field.
These functions take descriptors only.
Add scsi_sense_desc_sbuf(), which will print a formatted
version of the given sense descriptor.
Pull out a majority of the scsi_sense_sbuf() function and
put it into scsi_sense_only_sbuf(). This allows callers
that don't use struct ccb_scsiio to easily utilize the
printing routines. Revamp that function to handle
descriptor sense and use the new sense fetching and
printing routines.
Move scsi_extract_sense() into scsi_all.c, and implement it
in terms of the new function, scsi_extract_sense_len().
The _len() version takes a length (which should be the
sense length - residual) and can indicate which fields are
present and valid in the sense data.
Add a couple of new scsi_get_*() routines to get the sense
key, asc, and ascq only.
mly.c: Rename struct scsi_sense_data to struct
scsi_sense_data_fixed.
sbp_targ.c: Use the new sense fetching routines to get sense data
instead of accessing it directly.
sbp.c: Change the firewire/SCSI sense data transformation code to
use struct scsi_sense_data_fixed instead of struct
scsi_sense_data. This should be changed later to use
scsi_set_sense_data().
ciss.c: Calculate the sense residual properly. Use
scsi_get_sense_key() to fetch the sense key.
mps_sas.c,
mpt_cam.c: Set the sense residual properly.
iir.c: Use scsi_set_sense_data() instead of building sense data by
hand.
iscsi_subr.c: Use scsi_extract_sense_len() instead of grabbing sense data
directly.
umass.c: Use scsi_set_sense_data() to build sense data.
Grab the sense key using scsi_get_sense_key().
Calculate the sense residual properly.
isp_freebsd.h: Use scsi_get_*() routines to grab asc, ascq, and sense key
values.
Calculate and set the sense residual.

- Implement bus_adjust_resource() methods as far as necessary and in non-PCI
bridge drivers as far as feasible without rototilling them.
- As NEW_PCIB does a layering violation by activating resources at layers
above pci(4) without previously bubbling up their allocation there, move
the assignment of bus tags and handles from the bus_alloc_resource() to
the bus_activate_resource() methods like at least the other NEW_PCIB
enabled architectures do. This is somewhat unfortunate as previously
sparc64 (ab)used resource activation to indicate whether SYS_RES_MEMORY
resources should be mapped into KVA, which is only necessary if their
going to be accessed via the pointer returned from rman_get_virtual() but
not for bus_space(9) as the later always uses physical access on sparc64.
Besides wasting KVA if we always map in SYS_RES_MEMORY resources, a driver
also may deliberately not map them in if the firmware already has done so,
possibly in a special way. So in order to still allow a driver to decide
whether a SYS_RES_MEMORY resource should be mapped into KVA we let it
indicate that by calling bus_space_map(9) with BUS_SPACE_MAP_LINEAR as
actually documented in the bus_space(9) page. This is implemented by
allocating a separate bus tag per SYS_RES_MEMORY resource and passing the
resource via the previously unused bus tag cookie so we later on can call
rman_set_virtual() in sparc64_bus_mem_map(). As a side effect this now
also allows to actually indicate that a SYS_RES_MEMORY resource should be
mapped in as cacheable and/or read-only via BUS_SPACE_MAP_CACHEABLE and
BUS_SPACE_MAP_READONLY respectively.
- Do some minor cleanup like taking advantage of rman_init_from_resource(),
factor out the common part of bus tag allocation into a newly added
sparc64_alloc_bus_tag(), hook up some missing newbus methods and replace
some homegrown versions with the generic counterparts etc.
- While at it, let apb_attach() (which can't use the generic NEW_PCIB code
as APB bridges just don't have the base and limit registers implemented)
regarding the config space registers cached in pcib_softc and the SYSCTL
reporting nodes set up.
* The AR_ISR_RAC interrupt processing method has a subtle bug in all
the MAC revisions (including pre-11n NICs) until AR9300v2.
If you're unlucky, the clear phase clears an update to one of the
secondary registers, which includes TX status.
This shows up as a "watchdog timeout" if you're doing very low levels
of TX traffic. If you're doing a lot of non-11n TX traffic, you'll
end up receiving a TX interrupt from some later traffic anyway.
But when TX'ing 11n aggregation session traffic (which -HEAD isn't yet
doing), you may find that you're only able to TX one frame (due to
BAW restrictions) and this may end up hitting this race condition.
The only solution is to not use RAC and instead use AR_ISR and the
AR_ISR_Sx registers. The bit in AR_ISR which represents the secondary
registers are not cleared; only the AR_ISR_Sx bits are. This way
any updates which occur between the read and subsequent write will
stay asserted and (correctly) trigger a subsequent interrupt.
I've tested this on the AR5416, AR9160, AR9280. I will soon test
the AR9285 and AR9287.
* The AR_ISR TX and RX bits (and all others!) are set regardless of
whether the contents of the AR_IMR register. So if RX mitigation is
enabled, RXOK is going to be set in AR_ISR and it would normally set
HAL_INT_RX.
Fix the code to not set HAL_INT_RX when RXOK is set and RX mitigation
is compiled in. That way the RX path isn't prematurely called.
I would see:
* An interrupt would come in (eg a beacon, or TX completion) where
RXOK was set but RXINTM/RXMINT wasn't;
* ath_rx_proc() be called - completing RX frames;
* RXINTM/RXMINT would then fire;
* ath_rx_proc() would then be called again but find no frames in the
queue.
This fixes the RX mitigation behaviour to not overly call ath_rx_proc().
* Start to flesh out more correct timer interrupt handling - it isn't
kite/merlin specific. It's actually based on whether autosleep support
is enabled or not.
This is sourced from my 11n TX branch and has been tested for a few weeks.
Finally, the interrupt handling change should likely be implemented
for AR5210, AR5211 and AR5212.
There are some timing concerns which I've yet to fully map out.
In any case, there's an existing software driven mitigation method
for TX interrupts and when TX'ing 11n frames, the whole frame itself
generates an interrupt rather then the subframes.
