Jz4740 is a multimedia application processor targeting for mobile devices like e-Dictionary, eBook, portable media player (PMP) and GPS navigator. Jz4740 is powered by Ingenic 360 MHz XBurst CPU core (JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture provides high integration, high performance and low power consumption.

JzRISC incorporated in Jz4740 is the advanced and power-efficient 32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K D-Cache, and can operate at speeds up to 400 MHz.

On-chip modules such as LCD controller, embedded audio codec, multi- channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich suite of peripherals for multimedia application. NAND controller (SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are also available.

This patch introduces XBurst CPU support in U-Boot. It's compatible with MIPS32, but requires a bit different cache maintenance, timer routines, and boot mechanism using USB boot tool, so XBurst support can go into a separate new home, cpu/xburst/.

* Fix checkpatch errors/warnings

Changes since v6:

* Rebased against the latest U-Boot/MIPS codebase (the previous patches up to v6 were based on v1.1.6). $gp usage, relocation code and so on are getting synced with the current MIPS support in U-Boot.

* Use -mach=mips32, pass -EL specifiers in PLATFORM_CPPFLAGS and PLATFORM_LDFLAGS. This port works in Little-endian.

* Remove NAND-boot stuff. Those bits will be submitted as a nand_spl support, once this Jz4740 base support is merged.

* jzsoc_init() is removed. calc_clocks() and rtc_init() will be called through board_early_init_f().

* jz_serial.c is almost the same with standard ns16550 driver, but we dont' use it, because it need a special tweak for jz4740 like this:

If this is acceptable, we'll change to use standard ns16550 later.

* Coding styles and build warnings fixed
