These series of patch add support for atheros ath79 based SOCs in u-boot,
at the present moment it's just available for ar933x and qca953x chip.

This patch serises is based on mips_io_v4 branch on u-boot-mips repository 
[1] and tested on ar933x and qca953x board.

Changes in v7:
- Use setbits_32
- Fix include path for SoC specific headers
- Use CKSEGxADDR instead of KSEGxADDR for ar933x
- Use CKSEGxADDR instead of KSEGxADDR for qca953x
- remove map_physmem for debug port
- Define spi_cs_activate/spi_cs_deactivate
- Rename MHZ to ATH79_SPI_MHZ

- Use KSEG1 address for debug port in ap121
- Use KSEG1 address for debug port in ap143

Changes in v6:
- Move ar933x as separate patch
- Add get_bootstrap in reset.c
- Use map_physmem instead of KSEG1ADDR

- Import document "qca,ar9330-uart.txt" from kernel
- Add support for debug UART
- remove ar933x_spi_platdata
- Import document "spi-ath79.txt" from kernel
- Add delay for bitbang operation
- Move CONFIG_SYS_TEXT_BASE into ap121.h, and remove config.mk
- Remove useless README file
- Remove useless checkboard function

Changes in v4:
- Use global_data to save CPU/DDR/AHB clock
- Use arch_global_data to save SOC's type, revison and id
- 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
