You will need changes to some configure files to add your target tuple, 
e.g. config.sub, config.gcc, etc.  Most of the work will be adding the 
gcc backend target files in config/target, you will need a .h, .c, and a 
.md file at a minimum.  You will also need some library changes, there 
are some target dependent parts of libstdc++ for instance.

There is extensive documentation available.  See the gcc/doc directory 
in the sources, or see the web site.  This isn't very readable, and it 
doesn't tell you how to do a port, but it has valuable info you will need.

The easiest way to start a port is probably to look at an existing port 
for a target that is similar to yours, and then pattern your port after it.
