Look at an existing MPC5200 u-boot board port (like the phytec pcm030)
and duplicate it.  It also helps to look at the original media5200
u-boot patches that Freescale shipped on the software CD-ROM.

You really need to update u-boot I think.  Getting the kernel down
below 1MB and still be useful will be hard.  I would do it for you,
it's not really all that hard, but I don't really have any time at the
moment.

It really wasn't.  I've got one, and you're the only person I know
outside of Freescale who has another.
