The documentation is not freely distributable, unfortunately.

In case you are interested, I am actively working on making jz4730
devices working on current kernels.
http://www.linux-mips.org/archives/linux-mips/2010-02/msg00243.html

Further to that post, I have made some progress towards minimising the
differences between my code and Lars-Peter Clausen's jz4740 code. So
hopefully we will be in a position to merge and collaborate soon.
