Changes in v4: - Use global_data to save CPU/DDR/AHB clock - Use arch_global_data to save SOC's type, revison and id - Add clk.c for ar933x - Auto calculate baudrate for serial driver - Move pinctrl code in serial driver into arch/mips/mach-ath79 - Use get_serial_clock to serial clock source - Use get_bus_freq instead of hardcode in SPI driver

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

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 - Move serial driver code into drivers/serial - Add a compatible spi driver - Add a reference board implemention
