The TOZED ZLT S12 PRO is an AC1200 router featuring 4 Ethernet ports with a
TOZED TL70-C cellular modem which supports the NCM mode.

The stock firmware does SIM locking on the modem by stopping dialing when a
different PLMN is detected. This is not the case on OpenWrt.

Specifications:
- CPU: MediaTek MT7621AT
- RAM: 256MB DDR3
- NOR Flash: MX25L12833FM2I 16MB SPI Flash
- Wi-Fi 2.4Ghz: MT7603E
- Wi-Fi 5Ghz: MT7612E
- Switch: MT7530 4x 1Gbit Ports

- USB: 1x optional USB2.0 external port
- Switches/Buttons: WPS, Reset, Power Switch
- LEDs: Power, Wi-Fi, Data, Signal 1-5, Phone

Installation and TFTP Recovery:
- Connect to serial console.
- Boot initramfs image by choosing option 1 when U-Boot prompts.
- Install sysupgrade image via OpenWrt.

Serial Pins:
Located at the bottom right when looking from the front, right under the
Reset/WPS buttons. The pinout from the left is:
- RX
- GND
- TX
Baudrate is 115200.

When connecting from a powered off state, disconnect RX as it blocks the
boot process.

Hardware specification:

- SoC: MediaTek MT7621AT (880 MHz)
- Flash: 16 MB (Macronix MX25L12835FM2I-10G)
- RAM: 128 MB (Nanya NT5CC64M16GP-DI)
- WLAN 2.4 GHz: 2x2 MediaTek MT7603EN
- WLAN 5 GHz: 2x2 MediaTek MT7615N
- Ethernet: 1x 10/100/1000 Mbps
- LED: Power, Wifi, WPS
- Button: Reset, WPS
- UART: 1:VCC, 2:GND, 3:TX, 4:RX (from LAN port)
  Serial console @ 57600,8n1

Flash instructions:

Connect to serial console and start up the device. As the bootloader got
locked you need to type in a password to unlock U-Boot access.
When you see the following output on the console:

relocate_code Pointer at: 87f1c000

type in the super secure password:

1234567890

Then select TFTP boot from RAM by selecting option 1 in the boot menu.
As Linksys decided to leave out a basic TFTP configuration you need to
set server- & client ip as well as the image filename the device will
search for. You need to use the initramfs openwrt image for the TFTP
boot process.

Once openwrt has booted up, upload the sysupgrade image via scp and run
sysupgrade as normal.

28df7f7ff2 ramips: mt7621: add support for ZyXEL WSM20
The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.

Specifications
==============

SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)

MAC address assignment
======================

The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.

The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.

Installation (web interface)
============================

The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.

The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.

1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
   https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy

NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.

Installation (UART method)
==========================

The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:

1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation

Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:

   nand read 1800000 53c0000 800
   mw.b 1800004 1 1
   nand erase 53c0000 800
   nand write 1800000 53c0000 800

This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.

Back to stock
=============

It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.

It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:

   mtd write zyxel.bin Kernel2
   echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

2c530fcb97 ramips: reduce Archer AX23 / MR70X SPI-frequency
It was brought to attention the Archer AX23 v1 fails to read jffs2 data
from time to time. While this is not reproducible on my unit, it is on
others.

Reducing the SPI frequency does the trick. While it worked with at lest
40 MHz, opt for the cautious side and choose a save frequency of 25 MHz.

Apply the same treatment to the Mercusys MR70X which uses a similar
design just in case.

88d76bb455 ramips: mt7621: enable unused PCIe port to fix potential boot failure
One user reported that his SIMAX1800T couldn't boot like the others. After
debugging, I found that this was caused by the disabled PCIe port. I cannot
reproduce this issue on my SIMAX1800T. But when I disabled pcie2 on the
ASUS RT-AC57U, I got the same result.

It seems that disabling these unused PCIe ports on some mt7621 revisions
will cause PCIe to fail to initialize. So we'd better to re-enable them on
all related mt7621 devices.

* Serial interface: on board but not populated, pinout (from the DC jack
side to the WAN port side) is "3.3V Input Output Gnd". Baud rate is 57600,
settings are 8 data bits, no parity bit, one stop bit, and no flow control.

Stock flash layout:
```
GD25Q128C(c8 40180000) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K)
.numeraseregions = 0
Creating 7 MTD partitions on "raspi":

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.

"Config2" seems to be the config storage used by the stock firmware.

"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".

OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```

The OpenWrt image must have 96 bytes of padding in the header.

MAC addresses on OEM firmware:
|      		| location on the flash 	| notes    	|
|------		|-----------------------	|----------	|
| lan (eth2) 	| factory + 0xe000      	| on label 	|
| wan (eth3) 	| factory + 0xe006      	|          	|
| 2.4g (rax0) 	| not on flash          	| lan + 1  	|
| 5g (ra0) 	| not on flash          	| lan + 2  	|

Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.

Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.

1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`

Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.

* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

  eth0.1/phy1	----	*:82	rf 0x4
  phy0		----	*:83	factory 0x4
  eth0.2	MAC	*:b8	"wanaddr"

**Installation:**

  Method 1: Firmware upgrade page:

    (if you cannot access the APs webpage)
    factory reset with the reset button
    connect ethernet to a computer
    OEM webpage at 192.168.0.1
    username and password 'admin'

    Navigate to gear icon, "Device Management", "Tools"
    select the factory.dlf image
    Upload and verify checksum

  Method 2: Serial to upload initramfs:

    Follow directions for TFTP recovery
    upload and boot initramfs and do a sysupgrade

**TFTP recovery:**

  Requires UART serial console, reset button does nothing

  rename initramfs-kernel.bin to 'uImageEPG600'
  make available on TFTP server at 192.168.99.8
  power board, interrupt boot with "4"
  execute `tftpboot` and `bootm` (with the load address)

**Return to OEM:**

  Images from OEM are provided, but not compatible
  with openwrt sysupgrade. So it must be modified.

  Alternatively, back up all mtd partitions before flashing

**Note on switch registers:**

  The necessary registers needed for the QCA8337 switch
  can be read from interrupted boot (tftpboot, bootm)
  by using the following lines in the switch driver ar8327.c
  in the function 'ar8327_hw_config_of'
  where 'qca,ar8327-initvals' is parsed from DTS
  before the new register values are written:

    pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));
    pr_info("0x08 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD5_MODE));

This means that the current static partition table is only correct for
devices without any bad blocks.

Typical results of this mismatch are degraded wireless performance and
wrong MAC addresses, when the factory partition is shifted due to a bad
block somewhere before it. If there is a bad block already before the
ubi partition, then OpenWrt may not run at all because the kernel can't
find the rootfs.

Use the on-flash partition table to fix these issues. Replace the two
reserved partitions by the full partition list, as the driver does not
allow merging them.

d4c63c7786 ramips: add support for TP-Link Deco M4R v4
This commit adds support for the V4 hardware revision of the Deco M4R.
V4 is a complete overhaul of the hardware compared to V1 and V2,
and is much more similar to the Archer C6 V3 and C6U V1.

Specifications:

  SoC: MediaTek MT7621AT (2 cores at 880 MHz, 4 threads)
  RAM: Kingston D1216ECMDXGJD (256 MB)
  Wireless 2.4 GHz: MediaTek MT7603EN
  Wireless 5 GHz: MediaTek MT7613BEN
  Flash: 16 MB SPI NOR

Installation:

Flash the *-factory.bin image in the U-Boot recovery webserver.
You can trigger this webserver by holding the reset button until the LED
flashes yellow, or by hooking up to serial pads on the board (clearly
labeled GND, RX and TX) and pressing `x` early in boot.

Once the factory image has been flashed, you can use the regular upgrade
procedure with sysupgrade images for subsequent flashes.

39e4f03fd3 ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2
Device is the same as Xiaomi Mi Router 4A Gigabit, except of:
- 5G WiFi is MT7663
- addresses of leds, wifi and eth ports are slightly changed

Specs:
  SoC:  MT7621
  CPU:  2 x 880 MHz
  ROM:  16 MB
  RAM:  128 MB
  WLAN: MT7603, MT7663

MAC addresses:
  WAN     ****  factory 0xe006 (label)
  LAN     *:f7  factory 0xe000
  2.4 GHz *:f8  factory 0x0000+0x4 (mtd-eeprom+0x4)
  5 GHz   *:f9  factory 0x8000+0x4 (mtd-eeprom+0x4)

Installation:

Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.

Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155

In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
  in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
  # mtd -e OS1 -r write /tmp/sysupgrade.bin OS1

Recovery:

Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition

One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
  now router can be rebooted

62dbcb8305 ramips: Fix root volume for tplink-er605-v2
This device has two sets of volumes: main ones (`kernel`, `rootfs`, etc) and
'backup' (`kernel.b`, `rootfs.b`, etc). Bootloader tries to determine which set of
volumes to use by looking at contens of `extra-para` and `extra-para.b` volumes.
These volumes contain JSON that looks like this:

```
{
	"dbootFlag": "1",
	"integerFlag": "1",
	"fwFlag": "GOOD",
	"score":1
}
```

It looks like the bootloader looks for `"fwFlag": "GOOD"` (as opposed to `BAD`)
then it compares `score` field - whichever 'good' volume has bigger score wins.
This determines which set of volumes to use to boot.

So for example if `extra-para` is good and has bigger score then `kernel`,
`rootfs`, etc volumes are used. This means bootloader needs to explain to the
kernel which volume to use for the rootfs. After looking at bootloader code with
disassembler I think it contains a bug. Relevant part of code looks something
like this:

```
  if (image_id == 0) {
    rootfs_volume_id = 8;
    rootfs_volume_name = "rootfs";
  }
  else {
    rootfs_volume_id = 0xf;
    rootfs_volume_name = "rootfs.b";
  }
  sprintf(
    &buffer,
    0x800,
    "console=ttyS0,115200 noinitrd ubi.mtd=3,2048 ubi.block=0,%s
    root=/dev/ubiblock0_%d DKMGT_IMAGE_ID=%d DKMGT_IMAGE_TYPE=ubi",
    rootfs_volume_name,
    rootfs_volume_id,
    image_id
    );
```

Where `image_id == 0` if 'normal' (not '*.b' set of volumes is used).
However from device dumps we know that from the factory `rootfs.b` has id 8 and
`rootfs` has id 15.

So from above we can see that ids and names of rootfs volumes do not match. More
over - they are hardcoded in the bootloader.

Both things are problematic for OpwnWRT which completely removes volumes on
update meaning that volume ids may actually change.

So instead of relying on bootloader to provide the kernel with root device this
patch forces kernel to determine root automatically - and it defaults to
`rootfs` volume which is correct for our purposes.

Overall this makes image boot fine from flash after sysupgrade from inirams.
assuming `extra-para*` volumes make bootloader use non-'*.b' set of volumes.

setting is 57600-8-N-1. The board has an unpopulated 2.54mm straight pin
header.

The pinout is: VCC (the square), RX, TX, GND.

Installation
------------
See the Wiki page [1] for more details, it comes down to:

1. Open the device, take off the heat sink
2. Connect the SPI flash chip to a flasher, e.g. a Raspberry Pi. Also
   connect the RESET pin for stability (thanks @FPSUsername for reporting)
3. Make a backup in case you want to revert to stock later
4. Flash the squashfs-factory.trx file to offset 0x50000 of the flash
5. Ensure the bootpartition variable is set to 0 in the U-Boot
   environment located at 0x30000

Note that the U-Boot is password protected, this can optionally be
removed. See the forum [2] for more details.

Notes
-----
- This device has a dual-boot partition scheme, but OpenWRT will claim
  both partitions for more storage space.

Known issues
------------
- 2g MAC address does not match stock due to missing support for that in
  macaddr_add
- Only the power LED is configured by default

Reducing SPI flash frequency allows the build to boot on both old variants
with W25Q128 chip and new variants with XM25QH128C chip.

The old 80000000 value only boots on devices with the W25Q128 flash.

This is also the change Cudy themselves made in their openwrt builds and
their .dts file.

Removed m25p,fast-read as it is not needed with slower speeds.

c13263ca07 ramips: add support for D-Link DIR-1935 A1
Add support for D-Link DIR-1935 A1 based on similarities to DIR-882 A1,
DIR-867 A1 and other DIR-8xx A1 models. Existing DIR-882 A1 openwrt
"factory" firmware installs without modificaitons via the D-Link
Recovery GUI and has no known incompatibilities with the DIR-1935 A1.

Changes to be committed:
       new file:   target/linux/ramips/dts/mt7621_dlink_dir-1935-a1.dts
       modified:   target/linux/ramips/image/mt7621.mk
       modified:   target/linux/ramips/mt7621/base-files/etc/board.d/01_leds

Specifications:
* Board: Not known
* SoC: MediaTek MT7621 Family
* RAM: 128 MB (DDR3)
* Flash: 16 MB (SPI NOR)
* WiFi: MediaTek MT7615 Family (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WiFi Toggle, WPS
* LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green),
        WiFi 5G (green)

Notes:
* 160MHz 5GHz is available in LuCi but does not appear to work (i.e. no
  SSID is visible in wifi scanning apps on other devices) with either
  official DIR-882 A1 firmware or a test build for the DIR-1935 A1 based
  on the 22.03.2 branch. 80 MHz 5GHz works.

Serial port:
* Untested (potential user damage/error)
* Expected to be identical to other DIR-8xx A1 models:
	* Parameters: 57600, 8N1
	* Location: J1 header (close to the Reset, WiFi and WPS buttons)
	* Pinout: 1 - VCC
		  2 - RXD
	          3 - TXD
		  4 - GND

Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
  button, then re-plug it. Keep the reset button pressed until the power
  LED starts flashing orange, manually assign a static IP address under
  the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

* Some modern browsers may have problems flashing via the Recovery GUI,
  if that occurs consider uploading the firmware through cURL:

    curl -v -i -F "firmware=@file.bin" 192.168.0.1
