There's plenty of hints that I haven't yet fleshed out and are hardcoded
in arswitch_8327.c. They're listed here (from OpenWRT) for completeness.
This is enough to get the thing up, running and pinging.
Note that the mdiobus for the on-switch switch changes - the AR8327
probes first, which exposes mdio1, and thus the arge1 mdiobus will probe
and attach as mdio2. That is what the AR9344 on-chip switch has to
attach to.
Tested:
* Qualcomm Atheros DB120
The on-board NIC is an 3x3 AR9380 with 5GHz only.
* enable pci code in AR9344_BASE
* enable ath_pci and the firmware loading bits in DB120
* add in the relevant hints in DB120.hints to inform the probe/attach
code where the PCIe fixup data is for the onboard chip.
This is only relevant for a default development board. I also have a
DB120 with the on-board PCIe wifi NIC disabled and it's exposed as
a real PCIe slot (to put normal PCIe NICs in); the fixup code will need
to be disabled to make this work correctly.
Tested:
* DB120
The uboot mapping is only 128KiB (0x20000) and not 2MiB (0x200000).
Dynamically adjust kernel and rootfs mappings based on the
geom_uncompress(4) magic.
This makes the built images more reliable by accepting changes on kernel
size transparently and matches the images built with zrouter and
freebsd-wifi-build.

board.
This is another AR9331 board similar to the Carambola2. It has different
ethernet and LED wiring though.
They make a variety of boards that mostly differ on the amount of RAM/flash
available. Alfa Networks graciously donated a handful of 64MB RAM/16MB flash
boards so I can finish off 802.11s support for the AR93xx chips and do up
a tech demonstration with it.
This is enough to bring up the board.
Tested:
* Alfa networks UB Hornet board - 64MB ram, 16MB flash version.
Thankyou to Alfa Networks for the development boards!

we can now add all the hardware bits for the DB120.
* arge0/argemdio0 is hooked up to an AR8327 switch - which there's currently
no support for. However, the bootloader on this board does set it up as
a basic switch so we can at least _use_ it ourselves.
So we should at least configure the arge0 side of things, including the GMAC
register.
* .. the GMAC config peels off arge0 from the internal switch and exposes it
as an RGMII to said AR8327.
* arge1/argemdio1 are hooked up to an internal 10/100 switch. So, that also
needs configuring.
* Add support for the NOR flash layout.
* Add support for the wifi (which works, with bugs, but it works.)
What's missing!
* No GPIO stuff yet!
* No sound (I2S) and no NAND flash support yet, sorry!
* The normal DB120 has an external AR95xx wifi chip on PCIe but with the
actual calibration data in the NOR flash. My DB120 has been modified
to let me use the PCIe slot as a normal PCIe slot. I'll add the "default"
settings later when I have access to a non-modified one.
* Other stuff, like why the wifi unit gets upset and spits out stuck beacons
and interrupt storms everywhere. Sigh.
Tested:
* DB120 board - AR9344 (mips74k SoC) booting off of SPI flash into multi-user
mode.

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.
* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.
* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah
* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.
* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.
* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

DB120 development board.
The AR934x SoCs are a MIPS74k based system with increased RAM addressing
space, some scratch-pad RAM, an improved gige switch PHY and 2x2 or 3x3
on-board dual-band wifi.
This support isn't complete by any stretch; it's just enough to bring
the board up for others to tinker with. Notably, the MIPS74k support
is broken. However it boots enough to echo some basic probe/attach
messages, before dying somewhere in the TLB code.
Thankyou to Qualcomm Atheros for their continued support of me doing
open source work with their hardware.
Tested:
* AR9344, mips74k
This is an AR7240 based device with an AR9285 on-board.
I've tested the initial boot and wifi support; however at the moment
the ethernet switch driver doesn't seem to be picking up carrier on the
active ethernet port. Basic flood pinging works however, so I think
we're on the right track.
Thank you to Adrian Woodley <adrian@diskworld.com.au> for purchasing me
one of these devices to bootstrap FreeBSD-HEAD on.
This is based on the AR933x (Hornet) SoC from Qualcomm Atheros.
It's a much nicer board to do development on - 64MB RAM, 16MB flash.
The development board breaks out the GPIO pins, ethernet, serial (via
a USB<->RS232 chip), USB host and of course a small wifi antenna.
Everything but the wifi works thus far.
Until an ADM6996 driver shows up, this allows for the two switch
ports to be used.

This implements the bus transmit/receive/sigchg/ipend methods with
a polled interrupt handler (ipend) rather than enabling hardware
interrupts.
The FIFO is faked at 16 bytes deep for now, just so the transmit
IO side doesn't suck too bad (the callout frequency limits how quickly
IO is flushed to the sender, rather than scheduling the callout more
frequently whilst there's active TX. But I digress.)
Tested:
* Atheros AP121 (AR9330) reference board, booting to multi-user interactive
