TP-Link TL-MR3020 v3 is a pocket-size router based on MediaTek MT7628N.
This PR is based on the work of @meyergru[1], with his permission.
Specification:
- MediaTek MT7628N/N (575 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 1x 10/100 Mbps Ethernet
Flash instruction:
The only way to flash the image in TL-MR3020 v3 is to use
tftp recovery mode in U-Boot:
1. Configure PC with static IP 192.168.0.225/24 and tftp server.
2. Rename "openwrt-ramips-mt76x8-tplink_tl-mr3020-v3-squashfs-tftp-recovery.bin"
to "tp_recovery.bin" and place it in tftp server directory.
3. Connect PC with the LAN port, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
4. Router will download file from server, write it to flash and reboot.

Drop the nd_sd gpio pinmux in case sdcard is used. They're mutually
exclusive and for most of the boards not even used as GPIOs.
If the pins are in sdcard mode, the pins ND_WE_N and ND_CS_N are still
GPIOs (#45 and #46).

The PCI pins need to be set to "PCI Host support one device" to allow
the use of one PCI device and flash memory.
The pci-fnc function is intended to be used if no PCI is used but
flash, nand or the codec functionality is.

This patch improves faf64056dd by correcting
the partition scheme for the "RouterBoot" section of the flash.
The partition scheme initially submitted is incorrect and does not reflect
the actual flash structure.
The "RouterBoot" section (name matching OEM) is subdivided in several
static segments, as they are on ar71xx RB devices albeit with different
offsets and sizes.
The naming convention from ar71xx has been preserved, except for the
bootloaders which are named "bootloader1" and "bootloader2" to avoid
confusion with the master "RouterBoot" partition.
The preferred 'fixed-partitions' DTS node syntax is used, with nesting
support as introduced in 2a598bbaa3.
"partition" is used for node names, with associated "label" to match
policy set by 6dd94c2781.
Leave a note in DTS to explain how the original author selected the SPI speed.

RT5350 neither have rgmii nor a mdio pinmux group. MT7628an doesn't
have a jtag group. Having these groups defined might cause a boot
panic.
The pin controller fails to initialise for kernels > 4.9 if invalid
groups are used. If a subsystem references a pin controller
configuration node, it can not find this node and errors out. In worst
case it's the SPI driver which errors out and we have no root

Mediatek has a reference platform that pairs an MT7620A with an MT7530W,
where the latter responds on MDIO address 0x1f while both chips respond on
0x0 to 0x4. The driver special-cases this arrangement to make sure it's
talking to the right chip, but two different ways in two different places.
This patch consolidates the detection without the current requirement of
both tests to be separately satisfied in the DTS.

Add the ranges property to the PCI bridges where missing. Add the unit
address to PCI bridge where missing.
Rework the complete rt3883 pci node. Drop the PCI unit nodes from the
dtsi. They are not used by any dts file and should be rather in the dts
than in the SoC dtsi. Express the PCI-PCI bridge in a clean devicetree
syntax. The ralink,pci-slot isn't used by any driver, drop it. Move the
pci interrupt controller out of the pci node. It doesn't share the same
reg and therefore should be an independent/SoC child node.
Move the pci related rt3883 pinctrl setting to the dtsi instead of
defining the very same for each rt3883 board.
If the device_type property is used for PCI units, the unit is treated
as pci bridge which it isn't. Drop it for PCI units.
Reference pci-bridges or the pci node defined in the dtsi instead of
recreating the whole node hierarchy. It allows to change the referenced
node in the dtsi without the need to touch all dts.

In the stock firmware, WN-AX1167GR has two os images each composed of
Linux kernel and rootfs.
These images are stored in "Kernel" and "app" partition of the
following partitions, respectively.

The flag for boot partition is stored in "Key" partition, and U-Boot
reads this and determines the partition to boot.
If the image that U-Boot first reads according to the flag is
"Bad Magic Number", U-Boot then tries to boot from the other image.
If the second image is correct, change the flag to the number
corresponding to that image and boot from that image.

Currently the only method to install openwrt for the first time is via
TFTP recovery. After first install you can use regular updates.
Flash instructions:
1) To flash the recovery image, start a TFTP server with IP address
192.168.0.66 and serve the recovery image named tp_recovery.bin.
2) Connect your device to the LAN port, then press the WPS and Reset
button and power it up. Keep pressing the WPS/Reset button for
10 seconds or until the lock LED is lighting up.
It will try to download the recovery image and flash it.
It can take up to 2-3 minutes to finish. When it reaches 100%, the
router will reboot itself.

Select target devices "Mikrotik RBM11G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" in the
output directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the
created license file.**
When rebooted the board will try booting via ethernet first. If your
board does not boot via ethernet automatically you will have to attach
to the serial port and set ethernet as boot device within RouterBOOT.
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin"
initramfs image
2. Connect to ethernet port on board
3. Power on the board
4. Wait for OpenWrt to boot
Right now OpenWrt will be running with a SSH server listening. Now
OpenWrt must be flashed to the devices flash:
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
to the device using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
Once the flashing completes the board will reboot. Disconnect from the
devices ethernet port or stop the DHCP/TFTP server to prevent the device
from booting via ethernet again.
The device should now boot straight to OpenWrt.

Preparing a TFTP recovery image for initial flashing:
Currently the only method to install openwrt for the first time is via
TFTP download in u-boot. After first install you can use regular updates.
WARNING: This method also overwrites the bootloader partition!
Create a TFTP recovery image:
1) Download a stock TP-Link Firmware file here:
https://www.tp-link.com/en/download/Archer-C2_V1.html#Firmware
2) Extract u-boot from the binary file:
#> dd if=c2v1_stock_firmware.bin of=c2v1_uboot.bin bs=1 skip=512 count=131072
3) Now merge the sysupgrade image and the u-boot into one binary:
#> cat c2v1_uboot.bin openwrt-squashfs-sysupgrade.bin > ArcherC2V1_tp_recovery.bin
The resulting image can be flashed via TFTP recovery mode.
Flash instructions:
1) To flash the recovery image, start a TFTP server from IP address
192.168.0.66 and serve the recovery image named
ArcherC2V1_tp_recovery.bin.
2) Connect your device to the LAN port, then press the WPS/Reset button
and power it up. Keep pressing the WPS/Reset button for 10 seconds.
It will try to download the recovery image and flash it.
It can take up to 20-25 minutes to finish. When it reaches 100%, the
router will reboot itself.

The rtl8367b driver never supported a mdio property and it is quite
likely that the switch never worked for the board.
Use the mii-bus property instead to manage the switch via a mdio bus.

The U-boot is based on Ralink SDK so we can flash the firmware using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put the firmware into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press 2, follow the instruction to
set device and tftp server IP address and input the firmware
file name. U-boot will then load the firmware and write it into
the flash.

This commit adds support for the Mikrotik RouterBOARD RBM33g.
=Hardware=
The RBM33g is a mt7621 based device featuring three gigabit ports, 2
miniPCIe slots with sim card sockets, 1 M.2 slot, 1 USB 3.0 port and a male
onboard RS-232 serial port. Additionally there are a lot of accessible
GPIO ports and additional buses like i2c, mdio, spi and uart.
==Switch==
The three Ethernet ports are all connected to the internal switch of the
mt7621 SoC:
port 0: Ethernet Port next to barrel jack with PoE printed on it
port 1: Innermost Ethernet Port on opposite side of RS-232 port
port 2: Outermost Ethernet Port on opposite side of RS-232 port
port 6: CPU
==Flash==
The device has two spi flash chips. The first flash chips is rather small
(512 kB), connected to CS0 by default and contains only the RouterBOOT
bootloader and some factory information (e.g. mac address).
The second chip has a size of 16 MB, is by default connected to CS1 and
contains the firmware image.
==PCIe==
The board features three PCIe-enabled slots. Two of them are miniPCIe
slots (PCIe0, PCIe1) and one is a M.2 (Key M) slot (PCIe2).
Each of the miniPCIe slots is connected to a dedicated mini SIM socket
on the back of the board.
Power to all three PCIe-enabled slots is controlled via GPIOs on the
mt7621 SoC:
PCIe0: GPIO9
PCIe1: GPIO10
PCIe2: GPIO11
==USB==
The board has one external USB 3.0 port at the rear. Additionally PCIe
port 0 has a permanently enabled USB interface. PCIe slot 1 shares its
USB interface with the rear USB port. Thus only either the rear USB port
or the USB interface of PCIe slot 1 can be active at the same time. The
jumper next to the rear USB port controls which one is active:
open: USB on PCIe 1 is active
closed: USB on rear USB port is active
==Power==
The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack. The input voltage range is 11-32 V.
=Installation=
==Prerequisites==
A USB -> RS-232 Adapter and a null modem cable are required for
installation.
To install an OpenWRT image to the device two components must be built:
1. A openwrt initramfs image
2. A openwrt sysupgrade image
===initramfs & sysupgrade image===
Select target devices "Mikrotik RBM33G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" in the output
directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the created
license file.**
Serial settings: 115200 8N1
The installation is a two-step process. First the
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" must be booted
via tftp:
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin"
initramfs image
2. Connect to WAN port (left side, next to sys-LED and power indicator)
3. Connect to serial port of board
4. Power on board and enter RouterBOOT setup menu
5. Set boot device to "boot over ethernet"
6. Set boot protocol to "dhcp protocol" (can be omitted if DHCP server
allows dynamic bootp)
6. Save config
7. Wait for board to boot via Ethernet
On the serial port you should now be presented with the OpenWRT boot log.
The next steps will install OpenWRT persistently.
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" to the device
using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin"
Once the flashing completes reboot the router and let it boot from flash.
It should boot straight to OpenWRT.
