ath79: add support for Winchannel WB2000
WB2000 is a dual-band 11N AP using AR9344. The factory firmware used the original DB120 partition table with a small kernel partition at the end of firmware and the kernel will easily get oversized in the future. Since it has to be flashed using UART I also swapped kernel/rootfs and changed the default load address. Specification: - SoC: Atheros AR9344 - RAM: 128 MB - Flash: 16 MB - Ethernet: 10/100/1000 Mbps (Atheros AR8035) - 2x USB 2.0 - WIFI: AR9344(2G) + AR9382(5G) - RTC: DS1338 Known issue: 5G ath9k led doesn't work due to commit ccab68f. Flash instruction: Set up a TFTP server on your computer and configure static IP. Connect UART (J11 TX/GND/RX) and press any key to enter U-boot shell. 1. Change the default boot command: setenv bootcmd 'bootm 0x9f050000 || bootm 0x9fd50000' saveenv 2. Set your router ipaddr and server ipaddr. e.g.: setenv ipaddr 192.168.1.1 setenv serverip 192.168.1.50 3. Load and flash the firmware: tftp 0x80060000 fw.bin erase 0x9f050000 +$filesize cp.b $fileaddr 0x9f050000 $filesize 4. Reset your router: reset Signed-off-by: Chuanhong Guo <gch981213@gmail.com> [Drop the i2c node unit address. Move the ath9k-leds node out of the spi node, it doesn't belong there.
