9470160c35 mediatek: Add support for Xiaomi Redmi Router AX6S
Also known as the "Xiaomi Router AX3200" in western markets,
but only the AX6S is widely installation-capable at this time.

SoC: MediaTek MT7622B
RAM: DDR3 256 MiB (ESMT M15T2G16128A)
Flash: SPI-NAND 128 MiB (ESMT F50L1G41LB or Gigadevice GD5F1GQ5xExxG)
WLAN: 2.4/5 GHz 4T4R
2.4 GHz: MediaTek MT7622B
5 GHz: MediaTek MT7915E
Ethernet: 4x 10/100/1000 Mbps
Switch: MediaTek MT7531B
LEDs/Keys: 2/2 (Internet + System LED, Mesh button + Reset pin)
UART: Marked J1 on board VCC RX GND TX, beginning from "1". 3.3v, 115200n8
Power: 12 VDC, 1.5 A

Notes:
U-Boot passes through the ethaddr from uboot-env partition,
but also has been known to reset it to a generic mac address
hardcoded in the bootloader.

However, bdata is also populated with the ethernet mac addresses,
but is also typically never written to. Thus this is used instead.

Installation:
1. Flash stock Xiaomi "closed beta" image labelled
'miwifi_rb03_firmware_stable_1.2.7_closedbeta.bin'.
(MD5: 5eedf1632ac97bb5a6bb072c08603ed7)

2. Calculate telnet password from serial number and login

3. Execute commands to prepare device
nvram set ssh_en=1
nvram set uart_en=1
nvram set boot_wait=on
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit

4. Download and flash image
On computer:
python -m http.server
On router:
cd /tmp
wget http://<IP>:8000/factory.bin
mtd -r write factory.bin firmware

Device should reboot at this point.

Reverting to stock:
Stock Xiaomi recovery tftp that accepts their signed images,
with default ips of 192.168.31.1 + 192.168.31.100.
Stock image should be renamed to tftp server ip in hex (Eg. C0A81F64.img)
Triggered by holding reset pin on powerup.

A simple implementation of this would be via dnsmasq's
dhcp-boot option or using the vendor's (Windows only)
recovery tool available on their website.

Similar to mt7623, also no longer use 'blockdev' and stop relying on
in-kernel partition parsers. Instead, strip off all metadata using
'fwtool' while writing the firmware image and scrape the number of
blocks written from 'dd', then use that block offset to stash the
configuration backup.

74f15628dd mediatek: add support for Buffalo WSR-2533DHP2
This adds support for the Buffalo WSR-2533DHP2.

The device uses the Broadcom TRX image format with a special magic. To
be able to boot the images or load them they have to be wrapped with
different headers depending how it is loaded.

There are multiple ways to install OpenWrt on this device.
Boot ramdisk from U-Boot
----------------------------
This will load the image and not write it into the flash.

1. Stop boot menu with "space" key
2. Select "System Load Linux to SDRAM via TFTP."
3. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-initramfs-kernel.bin
4. The system boots the image

Write to flash from U-Boot
-----------------------------
This will load the image over tftp and directly write it into the flash.

1. Stop boot menu with "space" key
2. Select "System Load Linux Kernel then write to Flash via TFTP."
3. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory-uboot.bin
4. The system writes this image into the flash and boots into it.

Write to flash from Web UI
-----------------------------
This will load the image over over the Web UI and write it into the flash

1. Open the Web UI
2. Go to "管理" -> "ファームウェア更新"
3. Select "ローカルファイル指定" and click "更新実行"
4. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory.bin
5. The system writes this image into the flash and boots into it.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in

 * Detect root device, handle sysupgrade, config restore, ...
 * Wire up (known) LEDs and buttons in OpenWrt-fashion.
 * Build one set of images from SD-card and eMMC.
 * Hopefully provide a good example of how things can be done right
   from scratch.

**Installation and images**

 * Have an empty SD-card at hand
 * Write stuff to the card, as root (card device is /dev/mmcblkX)
   - write header, gpt, bl2, atf, u-boot and recovery kernel:
     `cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX`
   - rescan partitions:
     `blockdev --rereadpt /dev/mmcblkX`
   - write main system to production partition:
     `cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5`

 * Installation to eMMC works using SD-card bootloader via TFTP
   When running OpenWrt of SD-card, issue this to trigger installation
   to eMMC:
   `fw_setenv bootcmd run emmc_init`
   Be prepared to serve the content of bin/targets/mediatek/mt7622 on
   TFTP server address 192.168.1.254.

**What's missing**

 * The red LED is always on, probably a hardware bug.
 * AHCI (probably needs DTS changes)
 * Ship SD-card image ready with every needed for eMMC install.
 * The eMMC has a second, currently unused boot partition. This would
   be ideal to store the WiFi EEPROM and Ethernet MAC address(es).
   @sinovoip ideas?

Thanks to Thomas Hühn @thuehn for providing the hardware!

0235186182 mediatek: add alternative UBI NAND layout for Linksys E8450
The vendor flash layout of the Linksys E8450 is problematic as it uses
the SPI-NAND chip without any wear-leveling while at the same time
wasting a lot of space for padding.
Use an all-UBI layout instead, storing the kernel+dtb+squashfs in
uImage.FIT standard format in UBI volume 'fit', the read-write
overlay in UBI volume 'rootfs_data' as well as reduntant U-Boot
environments 'ubootenv' and 'ubootenv2', and a 'recovery'
kernel+dtb+initramfs uImage.FIT for dual-boot.

** WARNING **
THIS PROCEDURE CAN EASILY BRICK YOUR DEVICE PERMANENTLY IF NOT CARRIED
OUT VERY CAREFULLY AND EXACTLY AS DESCRIBED!

Step 0

 * Configure your PC to have the static IPv4 address 192.168.1.254/24
 * Provide bin/targets/mediatek/mt7622 via TFTP

Now continue EITHER with step 1A or 1B, depending on your preference
(and on having serial console wired up or not).

Step 1A (Using the vendor web interface (or non-UBI OpenWrt install))

In order to update to the new bootloader and UBI-based firmware,
use the web browser of your choice to open the routers web-interface
accessible on http://192.168.1.1

 * Navigate to
   'Configuration' -> 'Administration' -> 'Firmware Upgrade'

 * Upload the file
    openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
   and proceed with the upgrade.

 * Once OpenWrt comes up, use SCP to upload the new bootloader files to
   /tmp on the router:
    *-mt7622-linksys_e8450-ubi-preloader.bin
    *-mt7622-linksys_e8450-ubi-bl31-uboot.fip

 * Connect via SSH as you will now need to replace the bootloader in
   the Flash.

    ssh root@192.168.1.1
    (the usual warnings)

 * First of all, backup all the flash now:

    for mtd in /dev/mtdblock*; do
     dd if=$mtd of=/tmp/$(basename $mtd);
    done

 * Then use SCP to copy /tmp/mtdblock* from the router and keep them
   safe. You will need them should you ever want to return to the
   factory firmware!

 * Now flow the uploaded files:
    mtd -e /dev/mtd0 write /tmp/*linksys_e8450-ubi-preloader.bin /dev/mtd0
    mtd -e /dev/mtd1 write /tmp/*linksys_e8450-ubi-bl31-uboot.fip /dev/mtd1

   If and only if both writes look like the completed successfully
   reboot the router. Now continue with step 2.

Step 1B (Using the vendor bootloader serial console)

 * Use the serial to backup all /dev/mtd* devices before using the
   stock firmware (you got root shell when connected to serial).

 * Then reboot and select 'U-Boot Console' in the boot menu.

 * Copy the following lines, one by one:

tftpboot 0x40080000 openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin
tftpboot 0x40100000 openwrt-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip
nand erase 0x0 0x180000
nand write 0x40080000 0x0 0x180000
reset

Now continue with step 2

Step 2

Once the new bootchain comes up, the loader will initialize UBI and the
ubootenv volumes. It will then of course fail to find any bootable
volume and hence resort to load kernel via TFTP from server
192.168.1.254 while giving itself the address 192.168.1.1

The requested file is called
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and your TFTP server should provide exactly that :)
It will be written to UBI as recovery image and booted.
You can then continue and flash the production OS image, either
by using sysupgrade in the booted initramfs recovery OS, or by using
the bootloader menu and TFTP.

That's it. Go ahead and mess around with a bootchain built almost
completely from source (only DRAM calibration blobs are fitted in bl2,
and the irreplacable on-chip ROM loader remains, of course).
And enjoy U-Boot built with many great features out-of-the-box.

You can access the bootloader environment from within OpenWrt using the
'fw_printenv' and 'fw_setenv' commands. Don't be afraid, once you got
the new bootchain installed the device should be fairly unbrickable
(holding reset button before and during power-on resets things and
allows reflashing recovery image via TFTP)

Special thanks to @dvn0 (Devan Carpenter) for providing amazingly fast
infra for test-builds, allowing for `make clean ; make -j$(nproc)` in
less than two minutes :)

3 GND

Settings are 115200 8N1.

Opening the case
----------------

Opening the case is not a nice task, as itis glued together. Insert a
flat knife between the front and back casing below the ethernet port.
Open up a gap this way and insert a flat scredriver, remove the knife.

Work your way around the casing by applying force to seperate the front
and back casing. This losens the glue and opens the plastic clips. Be
gentle, as these clips are very cheap and break quickly.

Installation
------------

1. Connect to the booted device at 192.168.1.20 using username/password
   "ubnt".

2. Transfer the OpenWrt sysupgrade image to the device using SCP.

3. Check the mtd partition number for bs / kernel0 / kernel1

   $ cat /proc/mtd

4. Set the bootselect flag to boot from kernel0

   $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock6

5. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1

   $ dd if=openwrt.bin of=/dev/mtdblock8
   $ dd if=openwrt.bin of=/dev/mtdblock9

6. Reboot the device. It should boot into OpenWrt.
