MPC555 support for RTEMS 4.6.2

[Avy Strominger]

Hello everybody,
I would like to use RTEMS on a Motorols MPC555 (using the Axiom board, 
but that shouldn't matter much, since the MPC555 is self contained).  I 
didn't see any MPC555 support in 4.6.2, only old mpc505, which is a 
totally different CPU.
Is there any MPC555 support available?  if so, how to integrate it into 
the 4.6.2 sources? 
What parameters should I use when compiling RTEMS for it?
Thanks for any help
