If you have U-boot configured as you say below, and an SMP linux, then  
the second CPU will automatically come up.  You don't need to do  
anything special.

As far as your reset problem, I'm running a MPC8641D board using the  
latest u-boot, and I am able to reset it just fine when booted SMP.   
You're going to have to provide more information or look into this  
yourself.

I can't tell you if your SCRATCH_VA is valid without knowing the  
entire memory map of your system.......
