From 80421fcc3ed1843f62a4a463548a4f33cdde362f Mon Sep 17 00:00:00 2001 From: Xiangfu Liu Date: Wed, 12 Oct 2011 12:24:06 +0800 Subject: MIPS: Ingenic XBurst Jz4740 processor support 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. For more info about Ingenic XBurst Jz4740: http://en.ingenic.cn/eng/ http://www.linux-mips.org/wiki/Ingenic 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/.
