during MPC8377 board bring up we couldn't get U-Boot up and running -
the serial line has been dead.
Using a bdi2000 debugger told us the CPU, RAM and Flash was basically
working fine.
Jocke had the same problems on a MPC8321 and found a solution/workaround
(adding 4 nops in Start.S right after _start).
I followed his proposal and it worked out fine.
The experts found an issue within init code and it looks like a proper
patch will be added to mainline shortly.
The discussion of the proper fix is right in this thread ...
This leaves the question why this only happens on Jocke's MPC8321 and my
MPC8377.
Looks like nobody else observed this. Our MPC8343 based boards never had
this issue.

Andr?
