If it is a 603e core with a handful of on-CPU peripherals, talk to
someone at FreeScale and try to get them to tell you if the on-CPU
peripherals are the same as or similar to those on any other part.

Many times they do not really advertise it but they are the same
or slightly modified.  They really could be new but you might get
lucky.

The ep1a or mpc8260 may also be good BSPs to look at.  It largely
depends on what the on-CPU peripherals look most like.
