ipq40xx: add support for EnGenius ENS620EXT Hardware -------- CPU: Qualcomm IPQ4018 RAM: 256M FLASH: 32M SPI NOR W25Q256 ETH: QCA8075 WiFi2: IPQ4018 2T2R 2SS b/g/n WiFi5: IPQ4018 2T2R 2SS n/ac LED: - Power amber - LAN1(PoE) green - LAN2 green - Wi-Fi 2.4GHz green - Wi-Fi 5GHz green BTN: - WPS UART: 115200n8 3.3V J1 VCC(1) - GND(2) - TX(3) - RX(4) Added basic support to get the device up and running for a sysupgrade image only. There is currently no way back to factory firmware, so this is a one-way street to OpenWRT. Install from factory condition is convoluted, and may brick your device: 1) Enable SSH and disable the CLI on the factory device from the web user interface (Management->Advanced) 2) Reboot the device 3) Override the default, limited SSH shell: a) Get into the ssh shell: ssh admin@192.168.1.1 /bin/sh --login b) Change the dropbear script to disable the limited shell. At the empty command prompt type: sed -i '/login_ssh/s/^/#/g’ dropbear /etc/init.d/dropbear restart exit 4) ssh in to a (now-) normal OpenWRT SSH session 5) Flash your built image a) scp openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin admin@192.168.1.1:/tmp/ b) ssh admin@192.168.1.1 c) sysupgrade -n /tmp/openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin 6) After flash completes (it may say "Upgrade failed" followed by "Upgrade completed") and device reboots, log in to newly flashed system. Note you will now need to ssh as root rather than admin.

ipq40xx: Fix reboot on EnGenius ENS620EXT This patch works around an issue where reboot would cause the AP to power down and not reboot. The ipq4019 restart controller reboot causes the system to power down and not recover. Fix is to disable the restart controller in the device tree and the device reverts to using the watchdog to perform the reset. The real problem is due to the buggy bootloader that ships with the device. Steve Glennon reported in the PR for this patch: <https://github.com/openwrt/openwrt/pull/2009> that: "the problem was due to a bad u-boot that ships with the device. Using the u-boot that comes with 3.5.5.3 EnGenius factory software now allows the old code (using the do_msm_reboot) to reboot successfully. On to the bad news: Well 3.5.5.3 is a bad path. Finally managed to recover. You CANNOT use prior EnGenius firmware to downgrade. Findings: * They now password protect the serial console with a new, unkown password. * They changed the protection on their walled-garden. I have to use the ssh admin@ip /bin/sh --login to get out of their walled-garden. * Attempts to flash the original 3.0.0 or 3.0.1 EnGenius firmware fail through the UI and sysupgrade. Their firmware update GUI now seem to detect regular openwrt images, but they fail to flash Attempts to flash a normal OpenWrt image with sysupgrade fail. [..] Attempts to sysupgrade with EnGenius firmware fail with the same "mandatory section(s) missing" error, so you cannot downgrade to 3.0.0 or 3.0.1."
