ipq806x: add support for Linksys EA7500 V1
This patch adds support for the Linksys EA7500 V1 router. Specification: - CPU: Qualcomm IPQ8064 - RAM: 256MB - Flash: NAND 128MB - WiFi: QCA9982 an+ac + QCA9983 bgn - Ethernet: 5 GBE Ports (WAN+ 4xLAN) (QCA8337) - USB: 1x USB 3.0 1x USB2.0 - Serial console: RJ-45 115200 8n1 (1V8 Voltage level) - 2 Buttons - 1 LED Known issues: - Some devices won't flash via web gui Installation: - Newer stock images doesn't allow to install custom firmware. - Please downgrade software to 1.1.2 version. Official firmware: https://downloads.linksys.com/downloads/firmware/FW_EA7500_1.1.2.172843_prod.gpg.img - Do it two times to downgrade all stored images. - Apply factory image via web-gui. Serial + TFTP method: - downgrade to 1.1.2 two times - connect ehternet and serial cable - set ip address of tftp server to 192.168.1.254 - put openwrt factory image to tftp folder and rename it to macan.bin - stop device while booting in u-boot - run command: "run flashimg" - run command: "setenv boot_part 1" - run command "saveenv" - reset Back to stock: - Please use old non-gpg image like this 1.1.2: https://downloads.linksys.com/downloads/firmware/FW_EA7500_1.1.2.172843_prod.img - ssh to router and copy image to tmp - use sysupgrade -n -F Tested by github users: @jack338c and @grzesiczek1 Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com> [removed i2c4_pins, mdio0_pins, nand_pins, rgmii2_pins from DTSI] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
