This way we at least use an address as base that is definitely owned by the device at hand. Flashing instruction: The Dlink "Emergency Room" cannot be accessed through the reset button on this device. You can either use console or use the encrypted factory image availble in the openwrt forum. Once the encrypted image is flashed throuh the stock Dlink web interface, the sysupgrade images can be used. Header pins needs to be soldered near the WPS and Wifi buttons. The layout for the pins is (VCC,RX,TX,GND). No need to connect the VCC. the settings are: Bps/Par/Bits : 57600 8N1 Hardware Flow Control : No Software Flow Control : No Connect your client computer to LAN1 of the device Set your client IP address manually to 192.168.0.101 / 255.255.255.0. Call the recovery page or tftp for the device at http://192.168.0.1 Use the provided emergency web GUI to upload and flash a new firmware to the device At the time of adding support the wireless config needs to be set up by editing the wireless config file: * Setting the country code is mandatory, otherwise the router loses connectivity at the next reboot. This is mandatory and can be done from luci. After setting the country code the router boots correctly. A reset with the reset button will fix the issue and the user has to reconfigure. * This is minor since the 5g interface does not come up online although it is not set as disabled. 2 options here: 1- Either run the "wifi" command. Can be added from LUCI in system - startup - local startup and just add wifi above "exit 0". 2- Or add the serialize option in the wireless config file as shown below. This one would work and bring both interfaces automatically at every boot: config wifi-device 'radio0' option serialize '1' config wifi-device 'radio1' option serialize '1' Signed-off-by: Karim Dehouche <karimdplay@gmail.com> [rebase, improve MAC table, update wireless config comment, fix 2.4g macaddr setup] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifications: - SoC: MT7621AT - RAM: 256MB - Flash: 128MB NAND - Ethernet: 5 Gigabit ports - WiFi: 2.4G/5G MT7615N - USB: 1 USB 3.0, 1 USB 2.0 This device is very similar to the EA7300 v1/v2, EA7500 v2, and EA8100 v1. 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. With thanks to Tom Wizetek (@wizetek) for testing.

* ramips: add support for Tenbay T-MB5EU-V01David Bauer2021-06-272-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware -------- MediaTek MT7621 SoC 256M DDR3 16MB BoHong SPI-NOR MediaTek MT7905+7975 2x2T2R DBDC bgnax / acax RGB LED WPS + RESET Button UART on compute module (silkscreened / 115200n8) The router itself is just a board with Power / USB / RJ-45 connectors and DC/DC converters. The SoC and WiFi components are on a daughterboard which connect using two M.2 connectors. The compute module has the model number "T-CB1800K-DM2 V02" printed on it. The main baord has "T-MB5EU V01" printed on it. This information might be useful, as it's highly likely either of these two will be reused in similar designs. The router itself is sold as Tenbay T-MB5EU directly from the OEM as well as "KuWFI AX1800 Smart WiFi 6 Eouter" on Amazon.de for ~50€ in a slightly different case. Installation ------------ A Tool for creating a factory image for the Vendor Web Interface can be found here: https://github.com/blocktrron/t-mb5eu-v01-factory-creator/ As the OEM Firmware is just a modified LEDE 17.01, you can also access failsafe mode via UART while the OS boots, by connecting to UART and pressing "f" when prompted. The Router is reachable at 192.168.1.1 via root without password. Transfer the OpenWrt sysupgrade image via scp and apply with sysupgrade using the -n and -F flags. Alternatively, the board can be flashed by attaching to the UART console, interrupting the boot process by keeping "0" pressed while attaching power. Serve the OpenWrt initramfs using a TFTP server with address 192.168.1.66. Rename the initramfs to ax1800.bin. Attach your TFTP server to one of the LAN ports. Execute the following commands. $ setenv ipaddr 192.168.1.67 $ setenv serverip 192.168.1.66 $ tftpboot 0x84000000 ax1800.bin $ bootm Wait for the device to boot. Then transfer the OpenWrt sysupgrade image to the device using SCP and apply sysupgrade. Signed-off-by: David Bauer <mail@david-bauer.net>

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 mtd erase ubi This should only be needed once.

* ramips: add support for Amped Wireless ALLY router and extenderJonathan Sturges2021-06-052-15/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Amped Wireless ALLY is a whole-home WiFi kit, with a router (model ALLY-R1900K) and an Extender (model ALLY-00X19K). Both are devices are 11ac and based on MediaTek MT7621AT and MT7615N chips. The units are nearly identical, except the Extender lacks a USB port and has a single Ethernet port. Specification: - SoC: MediaTek MT7621AT (2C/4T) @ 880MHz - RAM: 128MB DDR3 (Nanya NT5CC64M16GP-DI) - FLASH: 128MB NAND (Winbond W29N01GVSIAA) - WiFi: 2.4/5 GHz 4T4R - 2.4GHz MediaTek MT7615N bgn - 5GHz MediaTek MT7615N nac - Switch: SoC integrated Gigabit Switch - USB: 1x USB3 (Router only) - BTN: Reset, WPS - LED: single RGB - UART: through-hole on PCB. 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.

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.

Specifications: - SoC: MediaTek MT7621AT - RAM: 256 MB - Flash: 128 MB MB NAND (MX30LF1G18AC) - WiFi: MediaTek MT7603E - Switch: 1 LAN port (Gigabiti) - 5G/LTE: Quectel RG502Q-EA connected by USB3 to SoC - SIM: 2 micro-SIM slots under transparent cover - Buttons: Reset, WLAN under same cover - LEDs: Multicolour green/red/yellow under same cover (visible) - Power: 802.3at PoE via LAN port The device is built as an outdoor ethernet to 5G/LTE bridge or router. The Wifi interface is intended for installation and/or temporary management purposes only. UART Serial: 57600N1 Located on populated 5 pin header J5: [o] GND [ ] key - no pin [o] RX [o] TX [o] 3.3V Vcc Remove the SIM/button/LED cover, the WLAN button and 12 screws holding the back plate and antenna cover together. The GPS antenna is fixed to the cover, so be careful with the cable. Remove 4 screws fixing the antenna board to the main board, again being careful with the cables. A bluetooth TTL adapter is recommended for permanent console access, to keep the router water and dustproof. The 3.3V pin is able to power such an adapter. MAC addresses: OpenWrt OEM Address Found as lan eth2 08:26:97:*:*:BC Factory 0xe000 (hex), label wlan0 ra0 08:26:97:*:*:BD Factory 0x4 (hex) wwan0 usb0 random 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. Signed-off-by: Bjørn Mork <bjorn@mork.no>

When connecting to the device's serial port, it is strongly advised to use an isolated UART adapter. This prevents linking different power domains created by the PoE power supply, which may damage your devices. The device's U-Boot supports saving modified environments with `saveenv`. However, there is no u-boot-env partition, and saving modifications will cause the partition table to be overwritten. This is not an issue for running OpenWrt, but will prevent the vendor FW from functioning properly.

Device mac addresses: Stock firmware uses the same MAC address for ethernet (on device label) and 2.4GHz wireless. The 5GHz wireless address is incremented by one. This address is stored in the 'info' ('default-mac') partition at an offset of 8 bytes.

Set the fdt address $ fdt addr $(fdtcontroladdr) 4. Remove the signature node from the control FDT $ fdt rm /signature 5. Transfer and boot the OpenWrt initramfs image to the device. Make sure to name the file C0A80114.img and have it reachable at 192.168.1.1/24 $ tftpboot; bootm Installation ------------ 1. Connect to the booted device at 192.168.1.20 using username/password "ubnt". 2. Update the bootloader environment. $ fw_setenv devmode TRUE $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt" $ fw_setenv bootcmd "run boot_openwrt" 3. Transfer the OpenWrt sysupgrade image to the device using SCP. 4. Check the mtd partition number for bs / kernel0 / kernel1 $ cat /proc/mtd 5. Set the bootselect flag to boot from kernel0 $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4 6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1 $ dd if=openwrt.bin of=/dev/mtdblock6 $ dd if=openwrt.bin of=/dev/mtdblock7 7. Reboot the device. It should boot into OpenWrt. Below are the original installation instructions prior to the discovery of "devmode=TRUE". They are not required for installation and are documentation only. The bootloader employs signature verification on the FIT image configurations. This way, booting unauthorized image without patching the bootloader is not possible. Manually configuring the bootcmd in the U-Boot envronment won't work, as this is restored to the default value if modified. The bootloader is made up of three different parts. 1. The SPL performing early board initialization and providing a XModem recovery in case the PBL is missing 2. The PBL being the primary U-Boot application and containing the control FDT. It is LZMA packed with a uImage header. 3. A Ubiquiti standalone U-Boot application providing the main boot routine as well as their recovery mechanism. In a perfect world, we would only replace the PBL, as the SPL does not perform checks on the PBLs integrity. However, as the PBL is in the same eraseblock as the SPL, we need to at least rewrite both. The bootloader will only verify integrity in case it has a "signature" node in it's control device-tree. Renaming the signature node to something else will prevent this from happening. Warning: These instructions are based on the firmware intially shipped with the device and potentially brick your device in a way it can only be recovered using a SPI flasher. Only (!) proceed if you understand this! 1. Extract the bootloader from the U-Boot partition using the OpenWrt initramfs image. 2. Split the bootloader into it's 3 components: $ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056 $ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360 $ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416 3. Strip the uImage header from the PBL $ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1 4. Decompress the PBL $ lzma -d pbl.lzma --single-stream The decompressed PBL sha256sum should be d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235 5. Open the decompressed PBL using your favorite hexeditor. Locate the control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the label for the signature node is located. Rename the "signature" string at this offset to "signaturr". The patched PBL sha256sum should be d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97 6. Compress the patched PBL $ lzma -z pbl --lzma1=dict=67108864 The resulting pbl.lzma file should have the sha256sum 7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42 7. Create the PBL uimage $ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma -n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000 -T firmware -d pbl.lzma patched_pbl.uimage The resulting patched_pbl.uimage should have the sha256sum b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce 8. Reassemble the complete bootloader $ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1 conv=sync $ cat spl.bin > patched_uboot.bin $ cat aligned_pbl.uimage >> patched_uboot.bin $ cat ubnt.uimage >> patched_uboot.bin The resulting patched_uboot.bin should have the sha256sum 3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b 9. Transfer your patched bootloader to the device. Also install the kmod-mtd-rw package using opkg and load it. $ insmod mtd-rw.ko i_want_a_brick=1 Write the patched bootloader to mtd0 $ mtd write patched_uboot.bin u-boot 10. Erase the kernel1 partition, as the bootloader might otherwise decide to boot from there. $ mtd erase kernel1 11. Transfer the OpenWrt sysupgrade image to the device and install using sysupgrade.

* ramips: remove set_wifi_led function in 01_ledsAdrian Schmutzler2020-10-021-4/+0
| | | | | | | | | | | | | | | | | | | While we mostly use the ucidef_set_led_* functions directly in 01_leds we still have the set_wifi_led function in parallel for several old devices. This is not only inconsistent with the other definitions, it also links to the wlan0 interface instead of using a phy trigger which would be independent of the interface name (and is used for all newer devices anyway). Apart from that, the standard names "wifi" and "wifi-led" are not very helpful in a world with different radio bands either. Thus, this patch removes the set_wifi_led function and puts the relevant commands into the cases explicitly. This makes the mechanism used more evident and will hopefully lead to some future improvements or at least prevent some copy-pasting of the old setups.

| | | | | | | | | | | | | In ramips, it's not common to use an alias for specifying the WiFi LED; actually only one device uses this mechanism (TL-WR841N v14). Particularly since the WiFi LEDs are typically distinguished between 2.4G and 5G etc. it is also not very useful for this target. Thus, this patch removes the setup lines for this mechanism and converts the TL-WR841N v14 to the normal setup. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

The devicename is removed in DTS files and 01_leds, consolidation of definitions into DTSI files is done where (easily) possible, and migration scripts are updated. For the latter, all existing definitions were actually just devicename migrations anyway. Therefore, those are removed and a common migration file is created in target base-files. This is actually another example of how the devicename removal makes things easier. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

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.
