Native ABI do not need signal conversion, only emulators may want this. Usually
emulators implements its own sv_sendsig method. For now only ibcs2 emulator does
not have own sv_sendsig implementation and depends on native sendsig() method.
So, remove any extra attempts to convert signal numbers from native sendsig()
methods except from i386 where ibsc2 is living.
when allocation fails, it suffices to perform VM_WAIT. The direct map

physical page can be used as a page table page.

to make them more consistent.

The replacement started at r283088 was necessarily incomplete without
replacing boolean_t with bool. This also involved cleaning some type
mismatches and ansifying old C function declarations.

* Change mips24k -> mips74k for hwpmc, but leave it disabled for now.
* don't build pci by default.
* build pci and qca955x_pci for AP135, as theres a PCIe NIC.
* don't build a hwpmc module, it doesn't really work out well
for the mips boards at the moment.
* add ipfw and DEFAULT_TO_ACCEPT.
The QCA955x looks a lot like the AR724x PCIe controller, except it
supports two root complexes. Unfortunately I only have one, so
although this code has started down the path of supporting more than
one, it's definitely not yet ready.
Tested:
* AP135 board (QCA9558 SoC), with the 11ac NIC swapped for an AR9380
PCIe NIC.
Notes:
* Yes, this driver isn't very pretty. I decided to commit what I have
versus holding onto something that isn't yet finished. It is enough
to bring up the above NIC and interrupt routing works, so it's a good
start.
* However, yes, the DDR flush routine hooks need to be fixed up.
I don't think I'm firing the right one at the moment.
pages which pass a NULL virtual address. If the BUS_DMA_KEEP_PG_OFFSET
flag is set, use the physical address to compute the page offset
instead. The physical address should always be valid when adding
bounce pages and should contain the same page offset like the virtual
address.

The carambola2 exposes all the gpio pins, but some are reserved for
core functions (eg usb, ethernet, etc.) Others are configured by default
to be available as normal GPIO pins to do interesting things with.
GPIO 18->23 is the I2S, SLIC and SPDIF device pins, but none of those
are currently used. So, just allow those to show up.
Tested:
* AR9344, Carambola 2
* (.. bitbang SPI to an Adafruit LCD via libgpio, because FreeBSD could
do with more shiny output devices that aren't network interfaces.)
TODO:
There are some other pins aren't currently included here, but should be.
The LED pins are for the internal switch inside the AR9344.
* GPIO 0+1 are "LED0 + LED1", but they're tied to high for bootstrapping.
* GPIO 13-17 are "LED2..7", but they're tied (H, L, L, L, H) for bootstrapping.
* GPIO 11 and 12 are UART RTS/CTS or I2S; but GPIO 12 is tied L for bootstrap.
This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.
This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

and export them to userland.
- Define __HAVE_REG32 on platforms that define a reg32 structure and check
for this in <sys/procfs.h> to control when to export prstatus32, etc.
- Add prstatus32_t and prpsinfo32_t typedefs for the 32-bit structures.
libbfd looks for these types, and having them fixes 'gcore' in gdb of a
32-bit process on a 64-bit platform.
- Use the structure definitions from <sys/procfs.h> in gcore's elf32 core
dump code instead of duplicating the definitions.

The MAC addresses were totally wrong. They're like the DIR-625C1 - at
0x1ffe0004 and 0x1ffe0018. They're however stored as text strings.
The ath0 MAC address is also not set, even though the calibration
partition is valid.
So, pick the board address / first MAC as the ath0 MAC, and derive
arge0/arge1 from that. That way they're hopefully unique enough
for people with multiple devices.
Tested:
* DIR-655A1
TODO:
* Do the same for the DIR-625A1 and DIR-625C1.
A couple of internal functions used by malloc(9) and uma truncated
a size_t down to an int. This could cause any number of issues
(e.g. indefinite sleeps, memory corruption) if any kernel
subsystem tried to allocate 2GB or more through malloc. zfs would
attempt such an allocation when run on a system with 2TB or more
of RAM.
Note to self: When this is MFCed, sparc64 needs the same fix.

This allows the TL-WDR3600 to use the correct MAC address for ath0, ath1
and arge0. arge1 isn't used; until I disable it entirely it'll just
show up with a randomly generated MAC.
A lot of these dinky atheros based MIPS boards don't have a nice, well,
anything consistent defining their MAC addresses for things.
The Atheros reference design boards will happily put MAC addresses
into the wifi module calibration data like they should, and individual
ethernet MAC addresses into the calibration area in flash.
That makes my life easy - "hint.arge.X.eeprommac=<addr>" reads from
that flash address to extract a MAC, and everything works fine.
However, aside from some very well behaved vendors (eg the Carambola 2
board), everyone else does something odd.
eg:
* a MAC address in the environment (eg ubiquiti routerstation/RSPRO)
that you derive arge0/arge1 MAC addresses from.
* a MAC address in flash that you derive arge0/arge1 MAC addresses from.
* The wifi devices having their own MAC addresses in calibration data,
like normal.
* The wifi devices having a fixed, default or garbage value for a MAC
address in calibration data, and it has to be derived from the
system MAC.
So to support this complete nonsense of a situation, there needs to be
a few hacks:
* The "board" MAC address needs to be derived from somewhere and squirreled
away. For now it's either redboot or a MAC address stored in calibration
flash.
* Then, a "map" set of hints to populate kenv with some MAC addresses
that are derived/local, based on the board address. Each board has
a totally different idea of what you do to derive things, so each
map entry has an "offset" (+ve or -ve) that's added to the board
MAC address.
* Then if_arge (and later, if_ath) should check kenv for said hint and
if it's found, use that rather than the EEPROM MAC address - which may
be totally garbage and not actually work right.
In order to do this, I've undone some of the custom redboot expecting
hacks in if_arge and the stuff that magically adds one to the MAC
address supplied by the board - instead, as I continue to test this
out on more hardware, I'll update the hints file with a map explaining
(a) where the board MAC should come from, and (b) what offsets to use
for each device.
The aim is to have all of the tplink, dlink and other random hardware
we run on have valid MAC addresses at boot, so (a) people don't get
random B:S:D❌x:x ethernet MACs, and (b) the wifi MAC is valid
so it works rather than trying to use an invalid address that
actually upsets systems (think: multicast bit set in BSSID.)
Tested:
* TP-Link TL_WDR3600 - subsequent commits will add the hints map
and the if_ath support.
TODO:
* Since this is -HEAD, and I'm all for debugging, there's a lot of
printf()s in here. They'll eventually go under bootverbose.
* I'd like to turn the macaddr routines into something available
to all drivers - too many places hand-roll random MAC addresses
and parser stuff. I'd rather it just be shared code.
However, that'll require more formal review.
* More boards.
Without this the autotuning fails for small amounts of RAM (32mb),
which all the AR91xx shipping products seemed to have.
Thanks to gjb for reminding me to re-test this stuff.
Tested:
* AR91xx, TP-Link TL-WR1043nd v1
This is based on the AP135 design - QCA9558 SoC, 3x3 2GHz wifi, but no
5GHz (11n or 11ac) chip is available.
It however still has 128MiB of RAM, 16MiB of NOR flash and the AR8327N
gigabit switch - so it's quite a beefy router device.
Tested:
* Well, a unit, naturally
Obtained from: Completely messing up an amazon.com order and getting this instead, and asking "hey, wonder if I could.."
* add ipfw
* delete ath / ath_ahb for now, until I can have Warner beat me
with the clue stick about putting in conditional build things into
the ath Makefile so the module builds can just have the HAL bits
that are relevant for a particular target.
These are actually almost the same units; except one is 3x3 5GHz, and
one is 2x2 5GHz.
Tested:
* TP-Link TL-WDR3600
TODO:
* The ath0/ath1 MAC addresses are ye garbage (00:02:03:04:05:06); fixing
that will take a little more time. It works fine with the ath0/ath1
MAC addresses set manually.
* Go through and yank the AR9344 on-board switch config (arswitch1);
it's not required here for this AP.
The AR934x (and maybe others in this family) have a more complicated
GPIO mux. The AR71xx just has a single function register for a handful
of "GPIO or X" options, however the AR934x allows for one of roughly
100 behaviours for each GPIO pin.
So, this adds a quick hints based mechanism to configure the output
functions, which is required for some of the more interesting board
configurations. Specifically, some use external LNAs to improve
RX, and without the MUX/output configured right, the 2GHz RX side
will be plain terrible.
It doesn't yet configure the "input" side yet; I'll add that if
it's required.
Tested:
* TP-Link TL-WDR3600, testing 2GHz STA/AP modes, checking some
basic RX sensitivity things (ie, "can I see the AP on the other
side of the apartment that intentionally has poor signal reception
from where I am right now.")
Whilst here, fix a silly bug in the maxpin routine; I was missing
a break.
A lot of these embedded boards don't have a unique MAC address per
device stored somewhere unique - sometimes they'll have one MAC
for both arge NICs; someties they'll have one MAC for both arge NICs
/and/ the ath NICs. In these instances, we need to derive device
specific MAC addresses from the base MAC address.
These functions will be used by some follow-up code that'll slot
into if_arge and if_ath.
Otherwise, the initial media speed would change if a PHY is hooked up,
sending PHY speed notifications. For the AP135 at least, the RGMII
PHY has a static speed/duplex configured and if the PHY plumbing
attaches the PHY to the if_arge interface, the first link speed change
from 1000/full will set the MAC to something that isn't useful.
This shouldn't affect any other platforms - everything I looked at is
using hard-coded speed/duplex as static, as they're facing a switch
with no PHY attached.
