The 2.4GHz interface doesn't come up properly with the log showing:
mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK)
As seen on other MT7621 boards this is caused by a missing reset GPIO.
The MT7621 dtsi set GPIO 19 as PCIe reset GPIO, which on this board
reset the 5GHz interface on port 0. Add GPIO 8 to the PCIe reset GPIO
list to also reset the 2.4GHz interface on port 1.

These boards have AR8327 or QCA8337 external ethernet switch.
The SOC also has it's own internal switch
where VLAN is now enabled by default.
Changes to preinit caused all switches to have VLANs enabled by default
even if they are not configured with a topology in uci_defaults
(see commit f017f617ae)
When both internal and external switches have VLANs,
and the external switch has both LAN and WAN,
the TX traffic from the SOC cannot flow to the tagged port on the external switch
because the VLAN IDs are not matching.
So disable the internal switch VLANs by default on these boards.
Also, add a topology for the internal switch,
so that on LuCI there is not an "unknown topology" warning.
In theory, it may be possible to have LAN ports on both switches
through internal and external PHYs, but there are no known boards that have this.

The function mt7620_mdio_mode is only called once
and both the function and mdio_mode block have been named incorrectly,
leading to confusion and useless commits.
These lines in the mdio_mode block of mt7620_hw_init
are only intended for boards with an external mt7530 switch.
(see commit 194ca6127e)
Therefore, move lines from mdio_mode to the place in soc_mt7620.c
where the type of mt7530 switch is identified,
and move lines from mt7620_mdio_mode to a main function.
mt7620_mdio_mode was called from mt7620_gsw_init
where the priv struct is available,
so the lines must stay in mt7620_gsw_init function.
In order to keep things as simple as possible,
keep the DTS property related function calls together,
by moving them from mt7620_gsw_probe to init.
Remove the now useless DTS properties and extra phy nodes.

Set the PHY base address to 12 for mt7530 and 8 for others,
which is based on the default setting for some devices
from printing the register with the following command
after it is written to by uboot during the boot cycle.
`md 0x10117014 1`
PHY_BASE option only uses 5 bits of the register,
bits 16 to 20, so use 8-bit integer type.
Set the option using the DTS property mediatek,ephy-base
and create the gsw node if missing.
Also, added a kernel message to display the EPHY base address.

(cherry picked from commit 0976b6c426)
When the new variable ephy_base was introduced,
it was not applied to the if block for mdio_mode.
The first line in the mdio_mode if block
sets the EPHY base address to 12 in the SOC by writing a register,
but the corresponding variable in the driver
was still set to the default of 0.
This causes subsequent lines that write registers with the function
_mt7620_mii_write
to write to PHY addresses 0 through 4
while internal PHYs have been moved to addresses 12 through 16.
All of these lines are intended only for PHYs on the SOC internal switch,
however, they are being written to external ethernet switches
if they exist at those PHY addresses 0 through 4.
This causes some ethernet ports to be broken on boards with AR8327 or QCA8337 switch.
Other suggested fixes move those lines to the else block of mdio_mode,
but removing the else block completely also fixes it.
Therefore, move the lines to the mt7620_hw_init function main block,
and have only one instance of the function mtk_switch_w32
for writing the register with the EPHY base address.
In theory, this also allows for boards that have both external switches
and internal PHYs that lead to ethernet ports to be supported.

A workaround was added to the switch driver

However, the ethernet driver already does this,

Revert the workaround, so that both the switch driver

When the mdio-bus node is missing, the driver returns -NODEV

Installation
------------
Using the webcmd interface
--------------------------
Warning: Do not update to the latest Wavlink firmware (version
20201201) as this removes the webcmd console and you will need to
use the serial port instead.
You will need to have built uboot/sqauashfs image for this device,
and you will need to provide an HTTP service where the image can
be downloaded from that is accessible by the device.
You cannot use the device manufacturers firmware upgrade interface
as it rejects the OpenWrt image.
1. Log into the device's admin portal. This is necessary to
authenticate you as a user in order to be able to access the
webcmd interface.
2. Navigate to http://<device-ip>/webcmd.shtml - you can access
the console directly through this page, or you may wish to
launch the installed `telnetd` and use telnet instead.
* Using telnet is recommended since it provides a more
convenient shell interface that the web form.
* Launch telnetd from the form with the command `telnetd`.
* Check the port that telnetd is running on using
`netstat -antp|grep telnetd`, it is likely to be 2323.
* Connect to the target using `telnet`. The username should
be `admin2860`, and the password is your admin password.
3. On the target use `curl` to download the image.
e.g. `curl -L -O http://<some-other-lan-ip>/openwrt-ramips-mt7620-\
wavlink_wl-wn579x3-squashfs-sysupgrade.bin`.
Check the hash using `md5sum`.
4. Use the mtd_write command to flash the image.
* The flash partition should be mtd4, but check
/sys/class/mtd/mtd4/name first. The partition should be
called 'Kernel'.
* To flash use the following command:
`mtd_write -r -e /dev/mtd<n> write <image-file> /dev/mtd<n>`
Where mtd<n> is the Kernel partition, and <image-file> is
the OpenWrt image previously downloaded.
* The command above will erase, flash and then reboot the
device. Once it reboots it will be running OpenWrt.
Connect via ssh to the device at 192.168.1.1 on the LAN port.
The WAN port will be configured via DHCP.
Using the serial port
---------------------
The device uses uboot like many other MT7260a based boards. To
use this interface, you will need to connect to the serial
interface, and provide a TFTP server. At boot follow the
bootloader menu and select option 2 to erase/flash the image.
Provide the address and filename details for the tftp server.
The bootloader will do the rest.
Once the image is flashed, the board will boot into OpenWrt. The
console is available over the serial port.

Previous supported device YOUKU yk1 is actually Youku YK-L1. Though they look
really different, the only hardware difference between the two models is flash
size, YK-L1 has 32 MiB flash but YK-L1c has 16MiB. It seems that YK-L1c can
compatible with YK-L1's firmware but it's better to split it to different models.
It is easy to identify the models by looking at the label on the bottom of the
device. The label has the model number "YK-L1" or "YK-L1c". Due to different flash
sizes, YK-L1c that using previous YK-L1's firmware needs to apply "force update"
to install compatible firmware, so please backup config file before system upgrade.

Signed-off-by: DENG Qingfang <dqfext@gmail.com>
(cherry picked from commit 06af45ec05)
The following devices have a Winbond W25Q256FV flash chip,
which does not have the RESET pin enabled by default,
and otherwise would require setting a bit in a status register.
Before moving to Linux 5.4, we had the patch:
0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch
which kept specific flash chips with explicit 3-byte and 4-byte address modes
to stay in 3-byte address mode while idle (after an erase or write)
by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch.
this was obsoleted by the patch:
481-mtd-spi-nor-rework-broken-flash-reset-support.patch
which uses the newer upstream flag SNOR_F_BROKEN_RESET
for devices with a flash chip that cannot be hardware reset with RESET pin
and therefore must be left in 3-byte address mode when idle.
The new patch requires that the DTS of affected devices
have the property "broken-flash-reset", which was not yet added for most of them.
This commit adds the property for remaining affected devices in ramips target,
specifically because of the flash chip model.
However, it is possible that there are other devices
where the flash chip uses an explicit 4-byte address mode
and the RESET pin is not connected to the SOC on the board,
and those DTS would also need this property.

The SERCOMM NA502 is a smart home gateway manufactured by SERCOMM and sold
under different brands (among others, A1 Telekom Austria SmartHome
Gateway). It has multi-protocol radio support in addition to LAN and WiFi.
Note: BLE is currently unsupported.
Specifications
--------------
- MT7621ST 880MHz, Single-Core, Dual-Thread
- MT7603EN 2.4GHz WiFi
- MT7662EN 5GHz WiFi + BLE
- 128MiB NAND
- 256MiB DDR3 RAM
- SD3503 ZWave Controller
- EM357 Zigbee Coordinator
MAC address assignment
----------------------
LAN MAC is read from the config partition, WiFi 2.4GHz is LAN+2 and matches
the OEM firmware. WiFi 5GHz with LAN+1 is an educated guess since the
OEM firmware does not enable 5GHz WiFi.
Installation
------------
Attach serial console, then boot the initramfs image via TFTP.
Once inside OpenWrt, run sysupgrade -n with the sysupgrade file.
Attention: The device has a dual-firmware design. We overwrite kernel2,
since kernel1 contains an automatic recovery image.
If you get NAND ECC errors and are stuck with bad eraseblocks, try to
erase the mtd partition first with
mtd unlock ubi

This device is very similar to the EA7300 v1/v2 and EA7500 v2.
Installation:
Upload the generated factory image through the factory web interface.
(following part taken from EA7300 v2 commit message:)
This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

J1: pin1 (square pad, towards rear)=3.3V, pin2=RX,
pin3=GND, pin4=TX. Settings: 57600/8N1.
Note regarding dual system partitions
-------------------------------------
The vendor firmware and boot loader use a dual partition scheme. The boot
partition is decided by the bootImage U-boot environment variable: 0 for
the 1st partition, 1 for the 2nd.
OpenWrt does not support this scheme and will always use the first OS
partition. It will set bootImage to 0 during installation, making sure
the first partition is selected by the boot loader.
Also, because we can't be sure which partition is active to begin with, a
2-step flash process is used. We first flash an initramfs image, then
follow with a regular sysupgrade.
Installation:
Router (ALLY-R1900K)
1) Install the flashable initramfs image via the OEM web-interface.
(Alternatively, you can use the TFTP recovery method below.)
You can use WiFi or Ethernet.
The direct URL is: http://192.168.3.1/07_06_00_firmware.html
a. No login is needed, and you'll be in their setup wizard.
b. You might get a warning about not being connected to the Internet.
c. Towards the bottom of the page will be a section entitled "Or
Manually Upgrade Firmware from a File:" where you can manually choose
and upload a firmware file.
d: Click "Choose File", select the OpenWRT "initramfs" image and click
"Upload."
2) The Router will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
3) Log into LuCI as root; there is no password.
4) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
5) Complete the Installation by flashing a full OpenWRT image. Note:
you may use the sysupgrade command line tool in lieu of the UI if
you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Extender (ALLY-00X19K)
1) This device requires a TFTP recovery procedure to do an initial load
of OpenWRT. Start by configuring a computer as a TFTP client:
a. Install a TFTP client (server not necessary)
b. Configure an Ethernet interface to 192.168.1.x/24; don't use .1 or .6
c. Connect the Ethernet to the sole Ethernet port on the X19K.
2) Put the ALLY Extender in TFTP recovery mode.
a. Do this by pressing and holding the reset button on the bottom while
connecting the power.
b. As soon as the LED lights up green (roughly 2-3 seconds), release
the button.
3) Start the TFTP transfer of the Initramfs image from your setup machine.
For example, from Linux:
tftp -v -m binary 192.168.1.6 69 -c put initramfs.bin
4) The Extender will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
5) Log into LuCI as root; there is no password.
6) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
7) Complete the Installation by flashing a full OpenWRT image. Note: you
may use the sysupgrade command line tool in lieu of the UI if you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Backup the OEM Firmware:
-----------------------
There isn't any downloadable firmware for the ALLY devices on the Amped
Wireless web site. Reverting back to the OEM firmware is not possible
unless we have a backup of the original OEM firmware.
The OEM firmware may be stored on either /dev/mtd3 ("firmware") or
/dev/mtd6 ("oem"). We can't be sure which was overwritten with the
initramfs image, so backup both partitions to be safe.
1) Once logged into LuCI, navigate to System -> Backup/Flash Firmware.
2) Under "Save mtdblock contents," first select "firmware" and click
"Save mtdblock" to download the image.
3) Repeat the process, but select "oem" from the pull-down menu.
Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
Follow the TFTP recovery steps for the Extender, and use the
backup image.
* OpenWrt "Flash Firmware" interface:
Upload the backup image and select "Force update"
before continuing.

* USB: One USB2 port.
Installation:
------------
Install the OpenWrt factory image for C6U is from the
TP-Link web interface.
1) Go to "Advanced/System Tools/Firmware Update".
2) Click "Browse" and upload the OpenWrt factory image:
openwrt-ramips-mt7621-tplink_archer-c6u-v1-squashfs-factory.bin.
3) Click the "Upgrade" button, and select "Yes" when prompted.
Recovery to stock firmware:
--------------------------
The C6U bootloader has a failsafe mode that provides a web
interface (running at 192.168.0.1) for reverting back to the
stock TP-Link firmware. The failsafe interface is triggered
from the serial console or on failed kernel boot. Unfortunately,
there's no key combination that enables the failsafe mode. This
gives us two options for recovery:
1) Recover using the serial console (J1 header).
The recovery interface can be selected by hitting 'x' when
prompted on boot.
2) Trigger the bootloader failsafe mode.
A more dangerous option is force the bootloader into
recovery mode by erasing the OpenWrt partition from the
OpenWrt's shell - e.g "mtd erase firmware". Please be
careful, since erasing the wrong partition can brick
your device.

WARNING!!
ISP managed firmware might at any time update itself to a version
where all known workarounds have been disabled. Never boot an ISP
managed firmware with a SIM in any of the slots if you intend to use
the router with OpenWrt. The bootloader lock can only be disabled with
root access to running firmware. The flash chip is physically
inaccessible without soldering.
Installation from OEM web GUI:
- Log in as "supervisor" on https://172.17.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Installation from OEM ssh:
- Log in as "root" on 172.17.1.1 port 22022
- scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp
- Prepare bootloader config by running:
nvram setro uboot DebugFlag 0x1
nvram setro uboot CheckBypass 0
nvram commit
- Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Copying OpenWrt to the recovery partition:
- Verify that you are running a working OpenWrt recovery image
from flash
- ssh to root@192.168.1.1 and run:
fw_setenv CheckBypass 0
mtd -r erase Kernel2
- Wait while the bootloader mirrors Image1 to Image2
NOTE: This should only be done after successfully booting the OpenWrt
recovery image from the primary partition during installation. Do
not do this after having sysupgraded OpenWrt! Reinstalling the
recovery image on normal upgrades is not required or recommended.
Installation from Z-Loader:
- Halt boot by pressing Escape on console
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- Sysupgrade to the OpenWrt sysupgrade image
NOTE: ATNR will write the recovery image to both primary and recovery
partitions in one go.
Booting from RAM:
- Halt boot by pressing Escape on console
- Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu
- Press "4" to select "4: Entr boot command line interface."
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Load it using "tftpboot 0x88000000 initramfs-recovery.bin"
- Boot with "bootm 0x8800017C" to skip the 380 (0x17C) bytes ZyXEL
header
This method can also be used to RAM boot OEM firmware. The warning
regarding OEM applies! Never boot an unknown OEM firmware, or any OEM
firmware with a SIM in any slot.
NOTE: U-Boot configuration is incomplete (on some devices?). You may
have to configure a working mac address before running tftp using
"setenv eth0addr <mac>"
Unlocking the bootloader:
If you are unebale to halt boot, then the bootloader is locked.
The OEM firmware locks the bootloader on every boot by setting
DebugFlag to 0. Setting it to 1 is therefore only temporary
when OEM firmware is installed.
- Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware
- Run "fw_setenv DebugFlag 0x1" in OpenWrt
NOTE:
OpenWrt does this automatically on first boot if necessary
NOTE2:
Setting the flag to 0x1 avoids the reset to 0 in known OEM
versions, but this might change.
WARNING:
Writing anything to flash while the bootloader is locked is
considered extremely risky. Errors might cause a permanent
brick!
Enabling management access from LAN:
Temporary workaround to allow installing OpenWrt if OEM firmware
has disabled LAN management:
- Connect to console
- Log in as "root"
- Run "iptables -I INPUT -i br0 -j ACCEPT"
Notes on the OEM/bootloader dual partition scheme
The dual partition scheme on this device uses Image2 as a recovery
image only. The device will always boot from Image1, but the
bootloader might copy Image2 to Image1 under specific conditions. This
scheme prevents repurposing of the space occupied by Image2 in any
useful way.
Validation of primary and recovery images is controlled by the
variables CheckBypass, Image1Stable, and Image1Try.
The bootloader sets CheckBypass to 0 and reboots if Image1 fails
validation.
If CheckBypass is 0 and Image1 is invalid then Image2 is copied to
Image1.
If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to
Image2.
If CheckBypass is 1 then all tests are skipped and Image1 is booted
unconditionally. CheckBypass is set to 1 after each successful
validation of Image1.
Image1Try is incremented if Image1Stable is 0, and Image2 is copied to
Image1 if Image1Try is 3 or larger. But the bootloader only tests
Image1Try if CheckBypass is 0, which is impossible unless the booted
image sets it to 0 before failing.
The system is therefore not resilient against runtime errors like
failure to mount the rootfs, unless the kernel image sets CheckBypass
to 0 before failing. This is not yet implemented in OpenWrt.
Setting Image1Stable to 1 prevents the bootloader from updating
Image1Try on every boot, saving unnecessary writes to the environment
partition.
Keeping an OpenWrt initramfs recovery as Image2 is recommended
primarily to avoid unwanted OEM firmware boots on failure. Ref the
warning above. It enables console-less recovery in case of some
failures to boot from Image1.

allows you to back up original firmware, or
(2) Using TFTP recovery - does not require disassembly.
(1) Using serial console:
To install OpenWrt, one needs to disassemble the
router and flash it via TFTP by using serial console:
- Locate unpopulated 4-pin header on the top of the board, near buttons.
- Connect UART adapter to the connector. Use 3.3V voltage level only,
omit VCC connection. Pin 1 (VCC) is marked by square pad.
- Put your initramfs-kernel image in TFTP server directory.
- Power-up the device.
- Press "1" to load initramfs image to RAM.
- Enter IP address chosen for the device (defaults to 192.168.0.1).
- Enter TFTP server IP address (defaults to 192.168.0.22).
- Enter image filename as put inside TFTP server - something short,
like firmware.bin is recommended.
- Hit enter to load the image. U-boot will store above values in
persistent environment for next installation.
- If you ever might want to return to vendor firmware,
BACK UP CONTENTS OF YOUR FLASH NOW.
For this router, commonly used by mobile networks,
plain vendor images are not officially available.
To do so, copy contents of each /dev/mtd[0-3], "firmware" - mtd3 being the
most important, and copy them over network to your PC. But in case
anything goes wrong, PLEASE do back up ALL OF THEM.
- From under OpenWrt just booted, load the sysupgrade image to tmpfs,
and execute sysupgrade.
(2) Using TFTP recovery
- Set your host IP to 192.168.0.22 - for example using:
sudo ip addr add 192.168.0.22/24 dev <interface>
- Set up a TFTP server on your machine
- Put the sysupgrade image in TFTP server root named as 'root_uImage'
(no quotes), for example using tftpd:
cp openwrt-ramips-rt305x-zte_mf283plus-squashfs-sysupgrade.bin /srv/tftp/root_uImage
- Power on the router holding BOTH Reset and WPS buttons held for around
5 seconds, until after WWAN and Signal LEDs blink.
- Wait for OpenWrt to start booting up, this should take around a
minute.
Return to original firmware:
Here, again there are two possibilities are possible, just like for
installation:
(1) Using initramfs-kernel image and serial console
(2) Using TFTP recovery
(1) Using initramfs-kernel image and serial console
- Boot OpenWrt initramfs-kernel image via TFTP the same as for
installation.
- Copy over the backed up "firmware.bin" image of "mtd3" to /tmp/
- Use "mtd write /tmp/firmware.bin /dev/mtd3", where firmware.bin is
your backup taken before OpenWrt installation, and /dev/mtd3 is the
"firmware" partition.
(2) Using TFTP recovery
- Follow the same steps as for installation, but replacing 'root_uImage'
with firmware backup you took during installation, or by vendor
firmware obtained elsewhere.
A few quirks of the device, noted from my instance:
- Wired and wireless MAC addresses written in flash are the same,
despite being in separate locations.
- Power LED is hardwired to 3.3V, so there is no status LED per se, and
WLAN LED is controlled by WLAN driver, so I had to hijack 3G/4G LED
for status - original firmware also does this in bootup.
- FXS subsystem and its LED is controlled by the
modem, so it work independently of OpenWrt.
Tested to work even before OpenWrt booted.
I managed to open up modem's shell via ADB,
and found from its kernel logs, that FXS and its LED is indeed controlled
by modem.
- While finding LEDs, I had no GPL source drop from ZTE, so I had to probe for
each and every one of them manually, so this might not be complete -
it looks like bicolor LED is used for FXS, possibly to support
dual-ported variant in other device sharing the PCB.
- Flash performance is very low, despite enabling 50MHz clock and fast
read command, due to using 4k sectors throughout the target. I decided
to keep it at the moment, to avoid breaking existing devices - I
identified one potentially affected, should this be limited to under
4MB of Flash. The difference between sysupgrade durations is whopping
3min vs 8min, so this is worth pursuing.
In vendor firmware, WWAN LED behaviour is as follows, citing the manual:
- red - no registration,
- green - 3G,
- blue - 4G.
Blinking indicates activity, so netdev trigger mapped from wwan0 to blue:wwan
looks reasonable at the moment, for full replacement, a script similar to
"rssileds" would need to be developed.
Behaviour of "Signal LED" in vendor firmware is as follows:
- Off - no signal,
- Blinking - poor coverage
- Solid - good coverage.
A few more details on the built-in LTE modem:
Modem is not fully supported upstream in Linux - only two CDC ports
(DIAG and one for QMI) probe. I sent patches upstream to add required device
IDs for full support.
The mapping of USB functions is as follows:
- CDC (QCDM) - dedicated to comunicating with proprietary Qualcomm tools.
- CDC (PCUI) - not supported by upstream 'option' driver yet. Patch
submitted upstream.
- CDC (Modem) - Exactly the same as above
- QMI - A patch is sent upstream to add device ID, with that in place,
uqmi did connect successfully, once I selected correct PDP context
type for my SIM (IPv4-only, not default IPv4v6).
- ADB - self-explanatory, one can access the ADB shell with a device ID
added to 51-android.rules like so:
SUBSYSTEM!="usb", GOTO="android_usb_rules_end"
LABEL="android_usb_rules_begin"
SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", ATTR{idProduct}=="1275", ENV{adb_user}="yes"
ENV{adb_user}=="yes", MODE="0660", GROUP="plugdev", TAG+="uaccess"
LABEL="android_usb_rules_end"
While not really needed in OpenWrt, it might come useful if one decides to
move the modem to their PC to hack it further, insides seem to be pretty
interesting. ADB also works well from within OpenWrt without that. O
course it isn't needed for normal operation, so I left it out of
DEVICE_PACKAGES.

Vendor firmware expects model name without manufacturer name inside
'supported_devices' part of metadata. This allows direct upgrade to

(cherry picked from commit cf3f1f82ea)
CONFIG_FORTIFY_SOURCE=y is already set in the generic kernel
configuration, but it is not working for MIPS on kernel 5.4, support for
MIPS was only added with kernel 5.5, other architectures like aarch64
support FORTIFY_SOURCE already since some time.
This patch adds support for FORTIFY_SOURCE to MIPS with kernel 5.4,
kernel 5.10 already supports this and needs no changes.
This backports one patch from kernel 5.5 and one fix from 5.8 to make
fortify source also work on our kernel 5.4.
The changes are not compatible with the
306-mips_mem_functions_performance.patch patch which was also removed
with kernel 5.10, probably because of the same problems. I think it is
not needed anyway as the compiler should automatically optimize the
calls to memset(), memcpy() and memmove() even when not explicitly
telling the compiler to use the build in variant.
This increases the size of an uncompressed kernel by less than 1 KB.
