ath79: add support for 8devices Rambutan board
Rambutan is a Wifi module based on QCA9550/9557 http://www.8devices.com/products/rambutan Specification: - 720/600/200 MHz (CPU/DDR/AHB) - 128 MB of DDR2 RAM - 128 MB of NAND Flash - 1x 100Mbps Ethernet - 1x 1000Mbps Ethernet (PHY on dev-kit) - 1x Wifi radio 2x2 MIMO, dualband 2.4 and 5 GHz - 2x U.FL connectors on module, chip antennas on dev-kit - 1x miniPCIe slot - 2x USB2.0 host - 2x UART - SPI, I2C, GPIO Flash instructions: Upgrade from ar71xx target: sysupgrade -F /tmp/openwrt-ath79-nand-8dev_rambutan-squashfs-sysupgrade.tar or upgrade from GUI (don't save config) Use factory image to flash from U-Boot: tftpboot 80060000 openwrt-ath79-nand-8dev_rambutan-squashfs-factory.ubi nand erase.part ubi nand write 80060000 ubi ${filesize} Signed-off-by: Petr Štetiar <ynezz@true.cz> [copy&pasted missing commit description] Signed-off-by: Andrey Bondar <a.bondar@8devices.com>master
