Ok a couple of questions. How do I find out the size of the NOR flash? 
It was in a global in the ppc arch.

Also, where is the best place to fixup the partitions? We have paritions 
that must be at the top and ones that must be at the bottom, so we 
dynamically setup the partitions based on the NOR size. The NOR size is 
variable.

And is it ok the name the paritions in the dts based on an index? I 
notice others use an address, but since I don't know the address up 
front I just used index numbers.

Cheers,
   Sean
