This has an AR7240 SoC with an AR9285 wireless NIC on-board.

802.11n router.
The flash layout defaults to a 1 MiB section for the kernel so I'm trying
very hard to squeeze a minimialistic (LZMA compressde) kernel image into
that.
I've verified that it boots through to single user mode fine.
Issues:
* USB doesn't yet work as a module - I need to add something else to the
USB AR71xx build before that will work.
* There's no switch PHY support - but for now it quite happily behaves
as a useful dumb switch out of the box. Phew.
* Since a previous flash attempt trashed my radio configuration block,
I haven't yet verified whether the wireless works correctly.
I'll test that out shortly (read: once I re-calibrate the board somehow.)
Thanks to ray@ and the zrouter project for doing some of the initial

Terasic DE-4 board. Allow LED configuration to be set using loader
tunables, not just from userspace, and preconfigure LED 8 as a kernel
heartbeat. For now, this is a Nexus-attached, BERI-only driver, but it
could be used with other hard and soft cores on Altera FPGAs as well, in
principle.

used with Terasic's DE-4 and other similar FPGA boards. This display
is 800x480 and includes a capacitive touch screen, multi-touch
gesture recognition, etc. This device driver depends on a Cambridge-
provided IP core that allows the MTL device to be hooked up to the
Altera Avalon SoC bus, and also provides a VGA-like text frame buffer.
Although it is compiled as a single device driver, it actually
implements a number of different device nodes exporting various
aspects of this multi-function device to userspace:
- Simple memory-mapped driver for the MTL 24-bit pixel frame buffer.
- Simple memory-mapped driver for the MTL control register set.
- Simple memory-mapped driver for the MTL text frame buffer.
- syscons attachment for the MTL text frame buffer.
This driver attaches directly to Nexus as is common for SoC device
drivers, and for the time being is considered BERI-specific, although
in principle it might be used with other hard and soft cores on
Altera FPGAs.
Control registers, including touchscreen input, are simply memory
mapped; in the future it would be desirable to hook up a more
conventional device node that can stream events, support kqueue(2)/
poll(2)/select(2), etc.
This is the first use of syscons on MIPS, as far as I can tell, and
there are some loose ends, such as an inability to use the hardware
cursor. More fundamentally, it appears that syscons(4) assumes that
either a host is PC-like (i386, amd64) *or* it must be using a
graphical frame buffer. While the MTL supports a graphical frame
buffer, using the text frame buffer is preferable for console use.
Fixing this issue in syscons(4) requires non-trivial changes, as the
text frame buffer support assumes that direct memory access can be
done to the text frame buffer without using bus accessor methods,
which is not the case on MIPS. As a workaround for this, we instead
double-buffer and pretend to be a graphical frame buffer exposing
text accessor methods, leading to some quirks in syscons behaviour.

The driver attempts to support all documented parts, but has only been
tested with the 512Mbit part on the Terasic DE4 FPGA board. It should be
trivial to adapt the driver's attach routine to other embedded boards
using with any parts in the family.
Also import isfctl(8) which can be used to erase sections of the flash.

The switch code detects as an AR8216 at the present moment, which isn't

The sample kernel configuration depends on an MD-based root file
system, which is not provided. However, any 64-bit, big-endian
userspace image (such as one generated for MALTA) should work.
This will hopefully be supplemented by additional device drivers for
gxemul-specific hardware simulations from Juli Mallett. We have
found oldtestmips quite useful for testing and improving aspects of

This is an AR71xx based board with 8MB flash, 64MB RAM, a
Mini-PCI+ slot (see below) and a single 10/100/1000baseT
ethernet port. It also has two USB ports.
This is an easier board than most to add as it doesn't have a
switch PHY on-board. This made it (mostly) trivial to craft a
working configuration.
Things to note:
* This, like most other reference boards, use uboot rather then
redboot. It means that you typically have to manually flash
both the kernel and rootfs partitions.
* Since there's currently no (nice) way to extract out the
ethernet MAC and RAM from the uboot environment, the RAM
will default to 32mb and the MAC will be something very
incorrect. I'll try to fix this up in a subsequent commit
or two, even if it's just some hard-coded nonsense in
ar71xx_machdep.c for now.
* The board is designed for a specific model of mini-PCI+
NIC which never made it into production. Normal mini-PCI
NICs will work fine; if you happen to have the NIC in question
then it will work fine with this board.
bits.
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.
* Add in a default GPIO section for AR91XX_BASE.hints, which doesn't
define the GPIO function masks or any GPIO pines.
* Add in the GPIO line definitions for LEDs and GPIO pins for the
TP-WR1043nd.
I've verified the LEDs work fine using gpioset.
the second-last 64k seems to be the default firmware board configuration
area.
Since I have no idea whether uboot uses it or not - and it's prefixed
with an atheros eeprom signature (0xaa55), I figure the safest thing
to do is mark it as read-only.
I've modified my local tplink firmware building program to generate
a board configuration section - which is separate to this partition.
It's located in the 64k _before_ this particular 64k.
The firmware build program from OpenWRT never initialises those
values and the firmware images from tplink also leave it 0x0, so I
don't currently know what the exact, correct details should be.
The default flash layout gives only 1 megabyte for the kernel, gzipped.
The uboot firmware running on this device only supports gzip, not lzma, so
we actually _do_ have to try and slim the kernel down a bit.
But, since I can't actually do that at the present, I'm opting to:
* extend the kernel from 1mb to 2mb;
* have rootfs fill the rest of that, save 64k;
* eventually I'll hide a 64k config partition at the end, between the
end of rootfs and the ART (radio configuration data.)
The uboot firmware doesn't care about the partition layout. It just
expects the kernel application image to sit at 0xbf020000 (right after
the 128k uboot image.) The uboot header isn't actually read either -
it's "faked" from a "tplink" flash image header. So as long as the
map configuration here matches what is being written out via the
tplink firmware generator, everything is a-ok.
A previous commit disabled compiling the AR9130 support in the default
HAL build in the kernel. Since the AR9130 support won't actually function
without AH_SUPPORT_AR9130 (and that abomination needs to be undone at some
point, in order to allow USB 11n NICs to also work), we now have to
explicitly compile it in.
But since the 11n RF backends don't (currently) join the RF linker set,
one has to compile in _an_ RF backend for the HAL to compile.
At some point it would be nice to correctly update the bus glue to make
this "correct", including having the DDR flush occur in the right spot
(ie, any AHB interrupt.)
Create std.XLP for configuration options, which is included by the

the PCI code in. Interesting thing is the machine
reboots too ;-)
