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 since V1: 1. Move all SoC specific header files into arch/mips/include/asm/arch-ath79 2. Check SOC type and extract common code into arch/mips/mach-ath79 3. Add a compatible spi driver 4. Move serial driver code into drivers/serial 5. Add a reference board implemention

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