These series of patch add support for atheros ath79 based SOCs in u-boot, at the present moment it's just available for ar933x chip.

Changes in v3: - Convert serial driver to driver model - Convert spi driver to driver model - Add support for device tree - Move SoC specific header files into arch/mips/mach-ath79/include/mach - Optimize assembly code - Same code style convertion

Changes in v2: - Move all SoC specific header files into arch/mips/include/asm/arch-ath79 - Check SOC type and extract common code into arch/mips/mach-ath79 - Add a compatible spi driver - Move serial driver code into drivers/serial - Add a reference board implemention

Wills Wang (4): mips: add base support for atheros ath79 based SOCs mips: ath79: add serial driver for ar933x SOC mips: ath79: add spi driver mips: ath79: add AP121 reference board
