MIPS: Jz4740: Add qi_lb60 board support
Add support for the qi_lb60 (a.k.a QI Ben NanoNote) clamshell device from Qi hardware: http://en.qi-hardware.com/wiki/Ben_NanoNote http://en.qi-hardware.com/wiki/Main_Page http://en.wikipedia.org/wiki/Qi_hardware This Jz4740-based clamshell device does not use NOR flash to boot. The initial bring-up assumes that U-Boot is directly loaded into SDRAM using USB boot tool, and starts from 0x80100000. About USB boot tool ------------------- Jz4740 is one of the XBurst processors with USB boot functionality supported. The CPU can boot from a small ROM in the LSI, initialize CPU and USB module, then wait for USB commands from the USB host. We can send 8 KB binary data to the CPU cache using USB boot tool. USB boot tool is available to the public at Ingenic website. Also there is an alternative Debian package named xburst-tools.
