ath79: add support for Arduino Yun
Arduino Yun is a microcontroller development board, based on Atmel
ATmega32u4 and Atheros AR9331.
Specifications:
- MCU: ATmega32U4
- SoC: AR9331
- RAM: DDR2 64MB
- Flash: SPI NOR 16MB
- WiFi:
- 2.4GHz: SoC internal
- Ethernet: 1x 10/100Mbps
- USB: 1x 2.0
- MicroSD: 1x SDHC
Notes:
- Stock firmware is based on OpenWrt AA.
- The SoC UART can be accessed only through the MCU.
YunSerialTerminal is recommended for access to serial console.
- Stock firmware uses non-standard 250000 baudrate by default.
- The MCU can be reprogrammed from the SoC with avrdude linuxgpio.
Installation:
1. Update U-Boot environment variables to adapt to new partition scheme.
> setenv bootcmd "run addboard; run addtty; run addparts; run addrootfs; bootm 0x9f050000 || bootm 0x9fea0000"
> setenv mtdparts "spi0.0:256k(u-boot)ro,64k(u-boot-env),15936k(firmware),64k(nvram),64k(art)ro"
> saveenv
2. Boot into stock firmware normally and perform sysupgrade with
sysupgrade image.
# sysupgrade -n -F /tmp/sysupgrade.bin
