This is untested but should at least allow an AR724X to boot.
The current code is lacking the detail needed to expose the PCIe bus.
It is also lacking any NIC, PLL or flush/WB code.
This works well enough to bring a system up to single-user mode
using an MDROOT.
Known Issues:
* The EHCI USB doesn't currently work and will panic the kernel during
attach.
* The onboard ethernet won't work until the PLL routines have been
fleshed out and shoe-horned into if_arge.
* The WMAC device glue (and quite likely the if_ath support)
hasn't yet been implemented.
Add kernel side support for Secure Neighbor Discovery (SeND), RFC 3971.
The implementation consists of a kernel module that gets packets from
the nd6 code, sends them to user space on a dedicated socket and reinjects
them back for further processing.
Hooks are used from nd6 code paths to divert relevant packets to the
send implementation for processing in user space. The hooks are only
triggered if the send module is loaded. In case no user space
application is connected to the send socket, processing continues
normaly as if the module would not be loaded. Unloading the module
is not possible at this time due to missing nd6 locking.
The native SeND socket is similar to a raw IPv6 socket but with its own,
internal pseudo-protocol.

* Implement a SoC probe function, from Linux, which determines the
SoC family, type and revision. This only probes the AR71xx series
SoC and (currently) panics on others.
* Migrate some of the AR71XX specific hardware init (USB device, determining
system frequencies) into using the cpuops introduced in an earlier commit.
Other SoC specific hardware stuff (per-device flush/WB, GPIO pin wiring,
Ethernet PLL setup, other things I've likely missed) will be introduced in
subsequent commits.

it must reset its congestion window back to the initial window.
RFC3390 has increased the initial window from 1 segment to up to
4 segments.
The initial window increase of RFC3390 wasn't reflected into the
restart window which remained at its original defaults of 4 segments
for local and 1 segment for all other connections. Both values are
controllable through sysctl net.inet.tcp.local_slowstart_flightsize
and net.inet.tcp.slowstart_flightsize.
The increase helps TCP's slow start algorithm to open up the congestion
window much faster.

sysctl's and remove any side effects.
Both sysctl's share the same backend infrastructure and due to the
way it was implemented enabling net.inet.tcp.log_in_vain would also
cause log_debug output to be generated. This was surprising and
eventually annoying to the user.
The log output backend is kept the same but a little shim is inserted
to properly separate log_in_vain and log_debug and to remove any side
effects.

1. On n64, use XKPHYS to map page table pages instead of KSEG0. Maintain
just one freepages list on n64.
The changes are mainly to introduce MIPS_PHYS_TO_DIRECT(pa),
MIPS_DIRECT_TO_PHYS(), which will use KSEG0 in 32 bit compilation
and XKPHYS in 64 bit compilation.
2. Change macro based PMAP_LMEM_MAP1(), PMAP_LMEM_MAP2(), PMAP_LMEM_UNMAP()
to inline functions.
3. Introduce MIPS_DIRECT_MAPPABLE(pa), which will further reduce the cases
in which we will need to have a special case for 64 bit compilation.

Each of these SoCs have different devices, different hardware initialisation
methods and, quite likely, different quirks. These functions will abstract
out the SoC differences and keep these differences out of the drivers (eg
USB init, if_arge, etc.)
Makefiles or *.mk files, use ${CC:T:Mfoo} instead, so only the basename
of the compiler command (excluding any arguments) is considered.
This allows you to use, for example, CC="/nondefault/path/clang -xxx",
and still have the various tests in bsd.*.mk identify your compiler as
clang correctly.
ICC if cases were also changed.
