cool.  Want to make sure we can encompass the 83xx/85xx/86xx local  
bus in there.

No problem.  The cpm2_* code in the kernel is used on 85xx's that  
have a CPM and I don't think we have that much ifdef for 85xx  
specific CPM foo.  Only thing I can think of is this bit in cpm2.h:

#if defined(CONFIG_8272) || defined(CONFIG_MPC8555)
#define CPM_DATAONLY_SIZE       ((uint)(8 * 1024) - CPM_DATAONLY_BASE)
#define CPM_FCC_SPECIAL_BASE    ((uint)0x00009000)
#else
