Currently all PCI devices get the same IRQ that affects performance badly.
This commit adresses this problem and cleans the code.
ar7100 has a special PCI interrupt controller@18060018 that works exactly
the same way as misc interrupt controller.
This patch does the following:
1. Defines pci-intc interrupt controller@18060018 in dtsi.
2. Removes interrupt-controller property from PCI node.
3. Sets a correct interrupt mask for PCI devices.
4. Removes all IRQ handling code from the PCI driver.
"qca,ar7100-misc-intc" should be used as the compatible property, becuase on ar7100
the controlled status register is read-only and the ack method used in
"qca,ar7240-misc-intc" won't work properly.
There are two very minor downsides of this patch that don't affect perormance:
1. We allocate an IRQ domain of 32 IRQ, whan we need only 5. But ar7100 aren't tiny un terms of RAM
and that is not very important and can be tuned if we implement "nr-interrupts" property".
2. It reuses the same irg chip name "MISC" for both controllers.
Run tested on DIR-825 B1.

We currently don't have any code configuring interface mode in ath79,
meaning that we relies on bootloader to set the correct interface mode.
This patch added code to set interface correctly so that everything works
even if bootloader configures it wrong.(e.g. on WNDR3800 u-boot set
the second GMAC mode to RMII but it should be RGMII.)
Introduced "qca,mac-idx" for the difference in MII_CTRL register value.

This adds a shared ar7161_ubnt_routerstation.dtsi as well as two other
.dts files that utilize it, ar7161_ubnt_routerstation.dts and
ar7161_ubnt_routerstation-pro.dts.
The modifications to generic-ubnt.mk, config-default, and base-files
necessary for image generation, parsing RedBoot FIS partitions, network
configuration, and sysupgrade are also included.
This reintroduces vital bits from platform_do_upgrade_combined() and its
supporting functions to /lib/upgrade/platform.sh, which were previously
removed from ath79 in 3e9d9f6225 "ath79:
sysupgrade: drop unused platform checks". The new function is called
"routerstation_do_upgrade" and will *only* work for the RouterStation
series of boards. It does however retain the ability to downgrade (e.g.
from master -> 17.01.x using sysupgrade -F).
All hardware is functional including the AR8216 switch (for the Pro),
wireless via ath5k/ath9k using the miniPCI slots, flash, USB, button,
and LED.
Switch and LAN/WAN configuration is the same as it is with the
equivalent ar71xx targets. MAC addresses are assigned based upon the
content stored in the RedBoot config partition.
Flashing via both sysupgrade and TFTP has been confirmed to work. Also,
the initramfs images are now raw .bin files instead of being wrapped in
a uImage (as they currently are in ar71xx), which makes them bootable
with RedBoot.
One notable difference to ar71xx is the inclusion of the RedBoot
"fconfig" utility (analogous to U-Boot’s fw_printenv/fw_setenv) in
DEVICE_PACKAGES. The FIS partitions are probed using the RedBoot MTD
parser’s DT binding, whose proper usage is mutually exclusive to
defining a separate fixed-partitions node for "RedBoot config". This
config partition contains the board's base MAC address. The lack of a
hard-coded flash location means that the mtd-mac-address property cannot
be used in the .dts, so instead fconfig is used to read the MAC
addresses from flash in userspace during first boot.

A few words about the shift-register:
AVM used a trick to control the shift-register for the LEDs with only 2
pins, SERCLK and MOSI. Q7S, normally used for daisy-chaining multiple
shift-registers, pulls the latch, moving the shift register-state to
the storage register. It also pulls down MR (normally pulled up) to
clear the storage register, so the latch gets released and will not be
pulled by the remaining bits in the shift-register. Shift register is
all-zero after this.
For that we need to make sure output 7 is set to high on driver probe.
We accomplish this by using gpio-hogging.
Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1).
Firmware can be uploaded like following:
ftp> quote USER adam2
ftp> quote PASS adam2
ftp> binary
ftp> debug
ftp> passive
ftp> quote MEDIA FLSH
ftp> put openwrt-sysupgrade.bin mtd1
Note that this procedure might take up to two minutes. After transfer is
complete you need to powercycle the device to boot OpenWRT.

Add ath9k wifi capabilities to WNDR3700 family.
* use kmod-owl-loader to load firmware from "art"
* add wifi to DTS
* add wifi LEDs
Avoid using the same MAC for eth0 LAN and wlan0 by
toggling the eth0 MAC into a locally administered MAC.
That is currently done by in user-space by adding a
uci config item into /etc/config/network
(More elegant solution might be setting it already in
preinit phase.)
Known issues:
* wifi firmware file may not get created on the first boot
after flashing on time to bring wifi normally up. Likely
the overlay jffs2 is not yet ready for creating the
firmware file. "wifi up" may still bring wifi up.
Wifi will work normally at subsequent boots.
* phy0 and phy1 may get assigned mixed, so that phy0 may
be the 5GHz radio instead of the normal 2.4GHz, and vice
versa for phy1. Does not happen always, but may happen.

Pisen WMM003N (sold under the name of Cloud Easy Power) is an
AR9331-based router and power bank combo device. The device uses a
stock firmware modified from OpenWRT for TP-Link TL-WR703N; however
some GPIO definition is different on this device with TL-WR703N. An
AXP202 PMIC (connected to a 5000mAh battery) and a SD slot are also
added, and the stock Flash/RAM configuration is 8MiB/64MiB.
The stock firmware is an old and heavily modified OpenWRT-based
firmware, which has telnetd defaultly open, and the root password is
"ifconfig" (quotation marks not included). The factory image format is
not known yet, however the stock firmware ships the OpenWRT's sysupgrade
command, and it can be used to install a newer firmware.
Due to the lack of the access to the STM8 embedded controller, the SD
slot is currently not usable (because it's muxed with the on-board USB
port) and the AXP PMIC cannot be monitored.

Not all vendors bothered to write the correct MAC addresses for the
ath9k wifi into the calibration data. And while ath9k does have some
special dt-properties to extract the addresses from a fixed position,
there are still devices that require userspace to edit or modify
the caldata.
In my case, the MAC address for the Wi-Fi device is stored in an

Hold down the reset button while powering on the device. It will load a
ramdisk image named 'koala-uImage-initramfs-lzma.bin' from 192.168.100.8.
Note: depending on the present software, the device might also try to
pull a file called 'koala-uimage-factory'. Only the name differs, it
is still used as a ramdisk image.
Wait for the ramdisk image to boot. OpenWRT can be written to the flash
via sysupgrade or mtd.
Due to the flip-flop bootloader which we not (yet) support, you need to
set the partition the bootloader is selecting. It is possible from the
initramfs image with
> fw_setenv bootcmd run bootcmd_1
Afterwards you can reboot the device.
