A very similar process is used for creating a binutils port:

Start with the existing MIPS port and add code to handle the variant you 
are interested in.  Have a look at the files: gas/config/tc-mips.c, 
bfd/elfxx-mips.c and opcodes/mips-opc.c.  (There are others, but these 
three are a good starting point).

You will also need to extend the configuration files to recognise your 
particular target and allow you to build a toolchain for your processor.

If you have questions the first place to look is the source code, but do 
please feel free to post to this list as well.

Cheers
