I was pulling out old boxes and came across the following:

LSI L64815 Memory Management, Cache Ctr., and Cache Tag Unit
Technical Manual.

It has all the bits and info. that one would need to program the
Sun4m MMU arch. It even has documentation on block fill/copy
instructions.

Quite a gem of a book..
