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
conf files. The files XLP, XLPN32 and XLP64 will have mostly ABI related
options.
Also move uart and pci to mips/nlm/std.xlp since all XLP configurations
needs these devices.

all the architectures.
The option allows to mount non-MPSAFE filesystem. Without it, the
kernel will refuse to mount a non-MPSAFE filesytem.
This patch is part of the effort of killing non-MPSAFE filesystems
from the tree.
No MFC is expected for this patch.

From now on, default values for FreeBSD will be 64 maxiumum supported
CPUs on amd64 and ia64 and 128 for XLP. All the other architectures
seem already capped appropriately (with the exception of sparc64 which
needs further support on jalapeno flavour).
Bump __FreeBSD_version in order to reflect KBI/KPI brekage introduced
during the infrastructure cleanup for supporting MAXCPU > 32. This
covers cpumask_t retiral too.
The switch is considered completed at the present time, so for whatever
bug you may experience that is reconducible to that area, please report
immediately.

This patch adds support for the Netlogic XLP mips64 processors in
the common MIPS code. The changes are :
- Add CPU_NLM processor type
- Add cases for CPU_NLM, mostly were CPU_RMI is used.
- Update cache flush changes for CPU_NLM
- Add kernel build configuration files for xLP.

still build it.
While it may be a perfect win in some scenarios, it still troubles users
(see PRs) in general cases. In addition we are still allocating resources
even if disabled by sysctl and still leak arp/nd6 entries in case of
interface destruction.

copy the mbuf to an intermediate buffer and then copy that to the Simple
Executive's transmit ring.
