ramips: add support for SIM SIMAX1800T and Haier HAR-20S2U1 SIM AX18T and Haier HAR-20S2U1 Wi-Fi6 AX1800 routers are designed based on Tenbay WR1800K. They have the same hardware circuits and u-boot. SIM AX18T has three carrier customized models: SIMAX1800M (China Mobile), SIMAX1800T (China Telecom) and SIMAX1800U (China Unicom). All of these models run the same firmware. Specifications: SOC: MT7621 + MT7905 + MT7975 ROM: 128 MiB RAM: 256 MiB LED: status 3 R/G/B Button: reset 1 + wps/mesh 1 Ethernet: lan 3 + wan *1 (10/100/1000Mbps) TTL Baudrate: 115200 TFTP Server: 192.168.1.254 TFTP IP: 192.168.1.28 or 192.168.1.160 (when envs is broken) MAC Address: use address source label 30:xx:xx:xx:xx:62 wan lan 30:xx:xx:xx:xx:65 factory.0x8004 wan 30:xx:xx:xx:xx:62 factory.0x8004 -3 wlan2g 30:xx:xx:xx:xx:64 factory.0x0004 wlan5g 32:xx:xx:xx:xx:64 factory.0x0004 set 7th bit TFTP Installation (initramfs image only & recommend): 1. Set local tftp server IP: 192.168.1.254 and NetMask: 255.255.255.0 2. Rename initramfs-kernel.bin to "factory.bin" and put it in the root directory of the tftp server. (tftpd64 is a good choice for Windows) 3. Start the TFTP server, plug in the power supply, and wait for the system to boot. 4. Backup "firmware" partition and rename it to "firmware.bin", we need it to back to stock firmware. 5. Use "fw_printenv" command to list envs. If "firmware_select=2" is observed then set u-boot enviroment: /# fw_setenv firmware_select 1 6. Apply sysupgrade.bin in OpenWrt LuCI. Web UI Installation: 1. Apply update by uploading initramfs-factory.bin to the web UI. 2. Use "fw_printenv" command to list envs. If "firmware_select=2" is observed then set u-boot enviroment: /# fw_setenv firmware_select 1 3. Apply squashfs-sysupgrade.bin in OpenWrt LuCI. Recovery to stock firmware: a. Upload "firmware.bin" to OpenWrt /tmp, then execute: /# mtd -r write /tmp/firmware.bin firmware b. We can also write factory image "UploadBrush-bin.img" to firmware partition to recovery. Upload image file to /tmp, then execute: /# mtd erase firmware /# mtd -r write /tmp/UploadBrush-bin.img firmware How to extract stock firmware image: Download stock firmware, then use openssl: openssl aes-256-cbc -d -salt -in [Downloaded_Firmware] \ -out "firmware.tar.tgz" -k QiLunSmartWL Signed-off-by: Chen Minqiang <ptpt52@gmail.com> Signed-off-by: Shiji Yang <yangshiji66@qq.com> 2022-09-15 17:10:52 +00:00			`// SPDX-License-Identifier: GPL-2.0-or-later OR MIT`
