ath79: add support for Letv LBA-047-CH Specifications: SOC: QCA9531 650 MHz ROM: 16 MiB Flash (Winbond W25Q128FV) RAM: 128 MiB DDR2 (Winbond W971GG6SB) LAN: 10/100M *2 WAN: 10/100M *1 LED: BGR color *1 Mac address: label C8:0E:77:xx:xx:68 art@0x0 lan C8:0E:77:xx:xx:62 art@0x6 wan C8:0E:77:xx:xx:68 art@0x0 (same as the label) wlan C8:0E:77:xx:xx:B2 art@0x1002 (load automatically) TFTP installation: * Set local IP to 192.168.67.100 and open tftpd64, link lan port to computer. Rename "xxxx-factory.bin" to "openwrt-ar71xx-generic-ap147-16M-rootfs-squashfs.bin". * Make sure firmware file is in the tftpd's directory, push reset button and plug in, hold it for 5 seconds, and then it will download firmware from tftp server automatically. More information: * This device boot from flash@0xe80000 so we need a okli loader to deal with small kernel partition issue. In order to make full use of the storage space, connect a part of the previous kernel partition to the firmware.
