AR9287 EEPROM layout.
The AR9287 only supports 2ghz, so I've removed the 5ghz code (but left
the 5ghz edge flags in there for now) and hard-coded the 2ghz-only
path.
Whilst I'm there, fix a typo (ar9285->ar9287.)
This meets basic TX throughput testing - iperf TX tests == 27-28mbit in 11g,
matching the rest of my 11g kit.
I'm assuming for now that the AR9287 is only open-loop TX power control
(as mine is) so I've hard-coded the attach path to fail if the NIC is
not open-loop.
This greatly simplifies the TX calibration path and the amount of code
which needs to be ported over.
This still isn't complete - the rate calculation code still needs to be
ported and it all needs to be glued together.

without waiting for device readiness (or at least not updating FIS receive
area in time). To workaround that, special quirk was added earlier to wait
for the FIS receive area update. But it was found that under same PCI ID
0x91231b4b and revision 0x11 there are two completely different chip
versions (firmware?): HBA and RAID. The problem is that RAID version in
some cases, such as hot-plug, does not update FIS receive area at all!
To workaround that, differentiate the chip versions by their capabilities,
and, if RAID version found, skip FIS receive area update waiting and read
device signature from the PxSIG register instead. This method doesn't work
for HBA version when PMP attached, so keep using previous workaround there.
It isn't linked into the build because it's missing the TX power
and PDADC programming code.
This code is mostly based on the ath9k codebase, compared against
the Atheros codebase as appropriate.
What's implemented:
* probe/attach
* EEPROM board value programming
* RX initial calibration
* radio channel programming
* general MAC / baseband setup
* async fifo setup
* open-loop tx power calibration
What's missing before it can be enabled by default:
* TX power / calibration setting code
* closed-loop tx power calibration routines
* TSF2 handling
* generic timer support from ath9k

(SEMB) is unable to communicate to Storage Enclosure Processor (SEP), in
response to hard and soft resets it should among other things return value
0x7F in Status register. The weird side is that it means DRQ bit set, which
tells that reset request is not completed. It would be fine if SEMB was the
only device on port. But if SEMB connected to PMP or built into it, it may
block access to other devices sharing same SATA port.
Make some tunings/fixes to soft-reset handling to workaround the issue:
- ahci(4): request CLO on the port after soft reset to ignore DRQ bit;
- siis(4): gracefully reinitialize port after soft reset timeout (hardware
doesn't detect reset request completion in this case);
- mvs(4): if PMP is used, send dummy soft-reset to the PMP port to make it
clear DRQ bit for us.
For now this makes quirks in ata_pmp.c, hiding SEMB ports of SiI3726/SiI4726
PMPs, less important. Further, if hardware permit, I hope to implement real
SEMB support.
values for the commands, compared to the internal command values

My eventual aim is to make the HAL_ANI_CMD internal enum match
the public API and then remove all this messiness.
This now allows HAL_CAP_INTMIT users to use a public HAL_CAP_INTMIT_
enum rather than magic constants.
The only magic constants currently used by if_ath are "enable" and
"present". Some local tools of mine allow for direct, manual fiddling
of the ANI variables and I'll convert these to use the public enum API
before I commit them.

which did AR5212 specific initialisation. This would cause some slight
silliness when enabling/disabling ANI.
Just to be completely correct - and to ensure the phy error mask/RX filter
register isn't incorrectly played with - make the ANI control function a
method, have it set appropriately for AR5212/AR5416, and call that from the
ANI control interface.
This should hopefully make it clearer to developers what is going on
and when TPC is being hacked on, make it obvious why it isn't working for
series 1, 2, 3.
I won't flip on setting TX power for TX series 1, 2, 3 until I've done
some further testing with Kite to ensure it doesn't break anything.
(Before people ask - yes, TPC is only needed for 5ghz regdomains and
yes, Kite is a 2.4ghz only chip, but there are potential use cases
for 2ghz TPC. I just need to sit down and ensure it's supported and
functional.)
control the antenna control bits for the four TX series and the
TPC settings for TX series 1, 2, 3.
The specifics:
* The TPC setting for TX series 0 is handled in ctl0.
* TPC is currently disabled, so the per-packet TX power is
set via the global per-rate TX power register, not per packet.
* The antenna control bits don't matter for AR5416 and later
so they should stay 0 (which they currently do); they may
be set for Kite but as there's no TX diversity supported
at the moment (it requires the NIC to be built with an
external antenna switch, matching how antenna diversity
is done on legacy NICs), so again keep them 0.
This is in preparation for supporting per-rate TPC on the
AR5416 and later. The Kite (and soon to come Kiwi) code
sets ctl8-11 to 0x0, which doesn't have any effect at
the moment. When TPC is enabled it would result in the
second, third and fourth TX series attmpts to be done with
a TX power of 0. This commit doesn't change that; it'll
be followed up with some commits to properly set the TPC
registers appropriately.

Rewrite atomic operations for powerpc in order to achieve the following:
- Produce a type-clean implementation (in terms of functions arguments
and returned values) for the primitives.
- Fix errors with _long() atomics where they ended up with the wrong
arguments to be accepted.
- Follow the sys/type.h specifics that define the numbered types starting
from standard C types.
- Let _ptr() version to not auto-magically cast arguments, but leave

not true on old PCI based controllers. DAC configuration is read
from EEPROM in device reset phase and driver can override DAC
configuration. However I guess there is an undocumented reason why
EEPROM configuration does not enable DAC so do not blindly override
DAC configuration. Recent PCIe based controllers are supposed to
support 64bit DMA so allow 64bit DMA only on PCIe based controllers.

This brings USB bus more in line with how newbus is supposed to be used.
Also, because of the two-pass probing the following message was produced
by devd in default configuration when almost any USB device was
connected:
Unknown USB device: vendor <> product <> bus <>
This should be fixed now.
Note that many USB device drivers pass some information from probe
method to attach method via ivars. For this to continue working we rely
on the fact that the subr_bus code calls probe method of a winning driver
again before calling its attach method in the case where multiple
drivers claim to support a device. This is done because device
description is set in successful probe methods and we want to get a correct
device description from a winning driver. So now this logic is re-used
for setting ivars too.

When supported by hardware, this allows to control per-port activity, locate
and fault LEDs via the led(4) API for localization and status reporting
purposes. Supporting AHCI controllers may transmit that information to the
backplane controllers via SGPIO interface. Backplane controllers interpret
received statuses in some way (IBPI standard) to report them using present
indicators.
