You don't need to modify the MMU handling. It's compatible across all the
ARM processors, and will work with the TI family of chips. You also don't
have the right under the licensing terms to make any modifications to the
private code.

What you may need to change are the caching routines. That code is not in
the private tree, and you have the right to change it to meet the needs of
that processor.
