I'm sure that you are right, Timur.    Every version of U-boot I've 
tried to use,
all the way back to 1.3.x, for the 8360 as well as the 8349EMDS, has had
the same problem.   And as soon as I comment out the OF stuff in the config
file, all is well.   (I haven't looked into it in detail, so I can't 
provide a lot
of info at the moment.     ......and my new custom MPC8358 board arrived
just about an your ago!   Friday afternoon, right on time!   ;-) ).

At this point, I know *nothing* about device trees or OF......
Is this something that lives outside of u-boot?

I guess someone probably needs to point me to some "device trees
for dummies" info........
