decoded ranges. Pass any request for a specific range that fails because
it is not in a decoded range for an ACPI Host-PCI bridge up to the parent
to see if it can still be allocated. This is based on the assumption that
many BIOSes are inconsistent/broken and that settings programmed into BARs
or resources assigned to other built-in components are more trustworthy than
the list of decoded resource ranges in _CRS. This effectively limits the
decoded ranges to only being used for "wildcard" ranges when allocating
fresh resources for a BAR, etc. At some point I would like to only be
this permissive during an early scan of firmware-assigned resources during
boot and to be strict about all later allocations, but that isn't viable
currently.

The ROUERSTATION and RSPRO variants contain:
* the board specific bits (eg the RTC for RSPRO, later on it'll
include the GPIO/LED definitions);
* the boot specific bits (eg, on-board flash, usb flash, etc).
For now the AR71XX_BASE file contains the common board config,
drivers and net80211/ath wireless drivers.
I'll follow this up with config files for the other boards I
have (eg the Ubiquiti LSSR71, as well as some Mikrotik boards
that use the AR71XX and atheros reference boards) which will
be quite easy to do now.
no reason why it should be limited to 64K of DFLTPHYS. DMA data tag is any

doing split software/hardware LED configuration, we can now simply
treat "softled" as an "output" mux type.
This works fine on this DWA-552. Previous generation (pre-11n NICs) don't
have a GPIO mux - only input/output configuration - so they ignore this
field.
The hardware (MAC) LED blinking involves a few things:
* Selecting which GPIO pins map to the MAC "power" and "network" lines;
* Configuring the MAC LED state (associated, scanning, idle);
* Configuring the MAC LED blinking type and speed.
The AR5416 HAL configures the normal blinking setup - ie, blink rate based
on TX/RX throughput. The default AR5212 HAL doesn't program in any
specific blinking type, but the default of 0 is the same.
This code introduces a few things:
* The hardware led override is configured via sysctl 'hardled';
* The MAC network and power LED GPIO lines can be set, or left at -1
if needed. This is intended to allow only one of the hardware MUX
entries to be configured (eg for PCIe cards which only have one LED
exposed.)
TODO:
* For AR2417, the software LED blinking involves software blinking the
Network LED. For the AR5416 and later, this can just be configured
as a GPIO output line. I'll chase that up with a subsequent commit.
* Add another software LED blink for "Link", separate from "activity",
which blinks based on the association state. This would make my
D-Link DWA-552 have consistent and useful LED behaviour (as they're
marked "Link" and "Activity."
* Don't expose the hardware LED override unless it's an AR5416 or later,
as the previous generation hardware doesn't have this multiplexing
setup.
Some of the NICs I have here power up with the LEDs blinking, which is
incorrect. The blinking should only occur when the NIC is attempting
to associate.
* On powerup, set the state to HAL_LED_INIT, which turns on the "Power" MAC
LED but leaves the "Network" MAC LED the way it is.
* On resume, also init it to HAL_LED_INIT unless in station mode, where
it's forced to HAL_LED_RUN. Hopefully the net80211 state machine will
call newstate() at some point, which will refiddle the LEDs.
I've tested this on a handful of 11n and pre-11n NICs. The blinking
behaviour is slightly more sensible now.
relying on what the register defaults are.
This forces the blink mode to be proportional to the TX and RX frames
which match the RX filter.
This (along with a few tweaks to if_ath_led.c to configure the correct
GPIO pins) allows my DWA-552 AR5416 NIC to blink the LEDs in a useful
fashion, however those LEDs are marked "Link" and "Act(ivity)", which
don't really map well to the "power" / "network" LED interface which
the MAC provides. Some further tinkering is needed to see what other
useful operating modes are possible.
