This 750gr3 GPIO17 switch was added based on vendor source,
but only the 760iGS (which shares the rbsysfs board identifier)
device has the physical wiring. The 750Gr3 actually does not
support PoE out.
Apart from that, note that the gpio base (480) would have required
this GPIO to be referenced as 497 if it was kept.

Hardware
--------
SoC: MediaTek MT7621ST
WiFi: MediaTek MT7603
Quantenna QT3840BC
Flash: 128M NAND
RAM: 64M
LED: Dual colour red and green
BTN: Reset
WPS
Eth: 4 x 10/100/1000 connected to MT7621 internal switch
MT7621 RGMII port connected to Quantenna module
GPIO: Power/reset of Quantenna module
Quantenna module
----------------
The Quantenna QT3840BC (or QV840) is a separate SoC running
another Linux installation. It is mounted on a wide mini-PCIe
form factor module, but is connected to the RGMII port of
the MT7621. It loads both a second uboot stage and an os
image from the MT7621 using tftp. The module is configured
using Quantenna specific RPC calls over IP, using 802.1q
over the RGMII link to support multiple SSIDs.
There is no support for using this module as a WiFi device
in OpenWrt. A package with basic firmware and management
tools is being prepared.
Serial ports
------------
Two serial ports with headers:
RRJ1 - 115200 8N1 - Connected to the Quantenna console
J1 - 57600 8N1 - Connected to the MT7621 console
Both share pinout with many other Zyxel/Mitrastar devices:
1 - NC (VDD)
2 - TX
3 - RX
4 - NC (no pin)
5 - GND
Dual system partitions
----------------------
The vendor firmware and boot loader use a dual partition
scheme storing a counter in the header of each partition. The
partition with the highest number will be selected for boot.
OpenWrt does not support this scheme and will always use the
first OS partition. It will reset both counters to zero the
first time sysupgrade is run, making sure the first partition
is selected by the boot loader.
Installation from vendor firmware
---------------------------------
1. Run a DHCP server. The WAP6805 is configured as a client device
and does not have a default static IP address. Make a note of
which address it is assigned
2. tftp the OpenWrt initramfs-kernel.bin image to this address.
Wait for the WAP6805 to reboot.
3. ssh to the OpenWrt initramfs system on 192.168.1.1. Make a
backup of all mtd partitions now. The last used OEM image is
still present in either "Kernel" or "Kernel2" at this point,
and can be restored later if you save a copy.
4. sysupgrade to the OpenWrt sysupgrade.bin image.
Installation from U-Boot
------------------------
This requires serial console access
1. Copy the OpenWrt initramfs-kernel.bin image as "ras.bin" to
your tftp server directory. Configure the server address as
192.168.0.33/24
2. Hit ESC when the message "Hit ESC key to stop autoboot"
appears
3. Type "ATGU" + Enter, and then "2" immediately after pressing enter.
4. Answer Y to the question "Erase Linux in Flash then burn new
one. Are you sure?", and answer the address/filename questions.
Defaults:
Input device IP (192.168.0.2)
Input server IP (192.168.0.33)
Input Linux Kernel filename ("ras.bin")
5. Wait until after you see the message "Done!" and power cycle
the device. It will hang after flashing.
6. Continue with step 3 and 4 from the vendor firmware procedure.
Notes on the WAP6805 U-Boot
---------------------------
The bootloader has been modified with both ZyXELs zyloader and the
device specific dual partition scheme. These changes appear to have
broken a few things. The zyloader shell claims to support a number
of ZyXEL AT commands, but not all of them work. The image selection
scheme is unreliable and inconsistent. A limited U-Boot menu is
available - and used by the above U-Boot install procedure. But
direct booting into an uploaded image does not work, neither with
ram nor with flash. Flashing works, but requires a hard reset after
it is finished.
Reverting to OEM firmware
-------------------------
The OEM firmware can be restored by using mtd write from OpenWrt,
flashing it to the "Kernel" partition. E.g.
ssh root@192.168.1.1 "mtd -r -e Kernel write - Kernel" < oem.bin
OEM firmwares for the WAP6805 are not avaible for public download,
so a backup of the original installation is required. See above.
Alternatively, firmware for the WAP6806 (Armor X1) may be used. This
is exactly the same hardware. But the branding features do obviously
differ.
LED controller
--------------
Hardware implementation is unknown. The dual-color LED is controlled
by 3 GPIOs:
4: red
7: blinking green
13: green
Enabling both red and green makes the LED appear yellow.
The boot loader enables hardware blinking, causing the green LED to blink
slowly on power-on, until the OpenWrt boot mode starts a faster software
blink.

The "proper" vendor prefix for Ubiquiti is "ubnt", this is used in
all targets except ramips and also recommended by the kernel.
This patch adjusts the various board/image/device name variables
accordingly. Since we touch it anyway, this also adds the space
in "EdgeRouter X" as a hyphen to those variables to really make
them consistent with the model name.
While at it, create a real shared definition for the devices in
image/mt7621.mk instead of deriving one device from another.

So far, image/device/board names for Mikrotik devices in mt7621 have
been used quite inconsistently.
This patch harmonizes the naming scheme by applying the same style
as used lately in ath79, i.e. using "RouterBOARD" as separate word
in the model name (instead of RB prefix for the number) and deriving
the board/device name from that (= make lower case and replace spaces
by hyphens).
This style has already been used for most the model/DEVICE_MODEL
variables in mt7621, so this is essentially just adjusting the remaining
variables to that.

While most of the target's contents are split into subtargets, the
base-files are maintained for the target as a whole.
However, OpenWrt already implements a mechanism that will use (and
even prefer) files in the subtargets' directories. This can be
exploited to make several scripts subtarget-specific and thus save
some space.
In certain cases, keeping files in parent (=target) base-files was
more convenient, and thus no splitting was performed for those.
Note that this will increase overall code lines, but reduce code
per subtarget.
base-files ipk size reduction:
master (mt7621) 60958 B
split (mt7620) 46358 B (- 14.3 kiB)
split (mt7621) 48759 B (- 11.9 kiB)
split (mt76x8) 44948 B (- 15.6 kiB)
split (rt288x) 43508 B (- 17.0 kiB)
split (rt305x) 45616 B (- 15.0 kiB)
