I got the answer after a glance at the Manual itself.
824x is so different to 8260/8270. No CPM at all on
it. The DUART's program model is compatible with 
16550. Also no IMMR value... I thought 824x could have
a model as 8260 or even 8xx. New things learned!

Still no luck. From the print message I set, it passed
MMU_init() and mpc10x_bridge_init(), then stopped.

Any clue on it?
