      MIPS: Ingenic XBurst Jz4740 processor support · 80421fcc
      Xiangfu Liu authored
      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/.
