MPC-55xx Tools

My employer is about to start doing an pre-study on a project that's
specified as using the MPC-55xx.  Since we're not likely to be paid by
the end customer for this particular part of the work, we don't want
to spend massive amounts of money.

What tools are available for this platform?

What tools are people using?

What sort of costs are we looking at?

Initially, we'd like to use an evaluation kit of some sort, with a
reasonable compiler set.

We'll have to end up being AutoSAR-compliant, but this is not
necessarily a requirement for the pre-study.  (We'll probably end up
developing our own AutoSAR modules anyway.)

Thanks in advance for any input.
