[U-Boot] [PATCH v3 0/4] add support for atheros ath79 based SOCs

[Wills Wang]

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

Cool, thanks! Just some minor nitpicks, but nothing really heavy.
I am looking forward to running this on my AR933x arduino yun, which I bought
exactly and only for this purpose :)
