Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to
now use tmpfs, it causes $(rootfs_type) to now return tmpfs when
running initramfs image instead of being empty.
This broke initramfs detection which is required so that when installing
on MikroTik devices firmware partition would first get erased fully
before writing.
So, lets test for $(rootfs_type) returning "tmpfs" instead.

- SFP cage
- USB port
- microSD slot
Unsupported:
- Beeper (requires PWM driver)
- ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1)
The linux driver requires an interrupt, and pendown GPIO
These are unknown, and not needed with the touchscreen
only used for temperature and voltage monitoring.

- 17: output passive PoE out (lan5) switch
Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common
To boot to intramfs image in RAM:
1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
Wait (~25 seconds) for beep and then release reset button.
The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
check by plugging in to port 2-5 and going to 192.168.1.1.
To install OpenWrt to flash:
1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.
OEM firmware differences:
- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.

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.

As this shell is somewhat unreliable and likely to be killed in a random amount

Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).
After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

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.

The correct model name of WF-2881 is WF2881 without hyphen. The former used
boardnames are not added to SUPPORTED_DEVICES, to make it explicit that the
sysupgrade-tar image, which is newly added in the previous commit, should
not be used to upgrade from older version.

WF-2881 sysupgrade image uses UBI rootfs, but still relies on
default_do_upgrade. Because of this, config backup is not restored after
sysupgrade. It can be fixed by switching to nand_do_upgrade and
sysupgrade-tar image. default_do_upgrade does not handle sysupgrade-tar
properly, so one should use factory image to upgrade from older version.

ALFA Network Quad-E4G is a universal Wi-Fi/4G platform, which offers
three miniPCIe (PCIe, USB 2.0, SIM) and a single M.2 B-key (dual-SIM,
USB 3.0) slots, RTC and five Gigabit Ethernet ports with PoE support.
Specification:
- MT7621A (880 MHz)
- 256/512 MB of RAM (DDR3)
- 16/32+ MB of FLASH (SPI NOR)
- optional second SPI flash (8-pin WSON/SOIC)
- 1x microSD (SDXC) flash card reader
- 5x 10/100/100 Mbps Ethernet, with passive PoE support (24 V) in LAN1
- optional 802.3at/af PoE module for WAN
- 3x miniPCIe slot (with PCIe and USB 2.0 buses, micro SIM and 5 V)
- 1x M.2/NGFF B-key 3042 (USB 3.0/2.0, mini + micro SIM)
- RTC (TI BQ32002, I2C bus) with backup battery (CR2032)
- external hardware watchdog (EM Microelectronic EM6324)
- 1x USB 2.0 Type-A
- 1x micro USB Type-B for system serial console (Holtek HT42B534)
- 11x LED (5 for Ethernet, 5 driven by GPIO, 1x power indicator)
- 3x button (reset, user1, user2)
- 1x I2C (4-pin, 2.54 mm pitch) header on PCB
- 4x SIM (6-pin, 2.00 mm pitch) headers on PCB
- 2x UART2/3 (4-pin, 2.54 mm pitch) headers on PCB
- 1x mechanical power switch
- 1x DC jack with lock (24 V)
Other:
- U-Boot selects default SIM slot, based on value of 'default_sim' env
variable: '1' or unset -> SIM1 (mini), '2' -> SIM2 (micro). This board
has additional logic circuit for M.2 SIM switching. The 'sim-select'
will work only if both SIM slots are occupied. Otherwise, always slot
with SIM inside is selected, no matter 'sim-select' value.
- U-Boot enables power in all three miniPCIe and M.2 slots before
loading the kernel
- this board supports 'dual image' feature (controlled by 'dual_image'
U-Boot environment variable)
- all three miniPCIe slots have additional 5 V supply on pins 47 and 49
- the board allows to install up to two oversized miniPCIe cards (vendor
has dedicated MediaTek MT7615N/D cards for this board)
- this board has additional logic circuit controlling PERSTn pins inside
miniPCIe slots. By default, PERSTn (GPIO19) is routed to all miniPCIe
slots but setting GPIO22 to high allows PERSTn control per slot, using
GPIO23-25 (value is inverted)
You can use the 'sysupgrade' image directly in vendor firmware which is
based on OpenWrt (make sure to not preserve settings - use 'sysupgrade
-n -F ...' command). Alternatively, use web recovery mode in U-Boot:
1. Power the device with reset button pressed, the modem LED will start
blinking slowly and after ~3 seconds, when it starts blinking faster,
you can release the button.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image.

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)
