ath79: add support for ASUS RT-AC59U / ZenWiFi CD6 ASUS RT-AC59U / RT-AC59U v2 are wi-fi routers with a large number of alternate names, including RT-AC1200GE, RT-AC1300G PLUS, RT-AC1500UHP, RT-AC57U v2/v3, RT-AC58U v2/v3, and RT-ACRH12. ASUS ZenWiFi AC Mini(CD6) is a mesh wifi system. The unit labeled CD6R is the router, and CD6N is the node. Hardware: - SoC: QCN5502 - RAM: 128 MiB - UART: 115200 baud (labeled on boards) - Wireless: - 2.4GHz: QCN5502 on-chip 4x4 802.11b/g/n currently unsupported due to missing support for QCN550x in ath9k - 5GHz: QCA9888 pcie 5GHz 2x2 802.11a/n/ac - Flash: SPI NOR - RT-AC59U / CD6N: 16 MiB - RT-AC59U v2 / CD6R: 32 MiB - Ethernet: gigabit - RT-AC59U / RT-AC59U v2: 4x LAN 1x WAN - CD6R: 3x LAN 1x WAN - CD6N: 2x LAN - USB: - RT-AC59U / RT-AC59U v2: 1 port USB 2.0 - CD6R / CD6N: none WiFi calibration data contains valid MAC addresses. The initramfs image is uncompressed because I was unable to boot a compressed initramfs from memory (gzip or lzma). Booting a compressed image from flash works fine. Installation: To install without opening the case: - Set your computer IP address to 192.168.1.10/24 - Power up with the Reset button pressed - Release the Reset button after about 5 seconds or until you see the power LED blinking slowly - Upload OpenWRT factory image via TFTP client to 192.168.1.1 Revert to stock firmware using the same TFTP method.
