just for Redboot.
At some point we're going to need to build options for different
boot environments - for example, the UBoot setups I've seen simply
have the MAC address hard-coded at a fixed location in flash.
The OpenWRT support simply yanks the if_arge MAC directly from that
in code, rather than trying to find a uboot environment to pull it
from.
memory detected from Redboot, or overrides the "otherwise" case
if no Redboot information was found.
Some AR71XX platforms don't use Redboot (eg TP-LINK devices using
UBoot; some later Ubiquiti devices which apparently also use
UBoot) and at least one plain out lies - the Ubiquiti LS-SR71A
Redboot says there's 16mb of RAM when in fact there's 32mb.
A more "clean" solution will be needed at a later date.
The AR913x/AR724x USB lives at a different offset to the AR71xx
USB, so this needs to be either adjusted for in a subsequent
commit, or updated in hints for kernels compiled for those
platforms.

mipsel' or 'machine mips mipseb' into the config file (with a few 64's
tossed in for good measure). This will let us build the proper
kernels with different worlds as part of make universe.
This reflects actual type used to store and compare child device orders.
Change is mostly done via a Coccinelle (soon to be devel/coccinelle)
semantic patch.

* Add a function to write to the relevant PLL register
* Break out the PLL configuration for the AR71XX into the CPU ops,
lifted from if_arge.c.
* Add the AR91XX PLL configuration ops, using the AR91XX register
definitions.
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.
* 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.

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.)
The existing code only checked the alignment of the first mbuf and
didn't enforce the size constraints.
This commit introduces a simple function to check the alignment and
size of all mbufs in the list. This fixes the initial issue in the
PR.

quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the

The RX overflow is reported in bit 2 on real hardware and Linux driver
for the same device already has this defined correctly.
This fixes frequent interrupt storms seen on RouterStation Pro boards.
