is it feasible to have 83xx/86xx go 'multiplatform' but not 82xx?   
There are more annoyances about CPM2 support that are not clean such  
that you couldn't build support for different 82xx systems into the  
same kernel.  Today we only support one 82xx system in ARCH=powerpc,  
but I'd rather we not move it until we clean up those issues.  (the  
same is true of 85xx).
