The MBX board is not a good model to use, as  it  has  all  kinds  of
special  hardare  which  are most probably not present on your board.
You need a very detailed understanding of your own hartdware  befoire
you can pick a model configuration.

read the README and the manual.

Please read the README and the manual, and probably the MPC860 User's

It's not that simple. You have to port U-Boot to your hardware.  This
is much more complicated than you seem to expect.
