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.
