I think there's some confusion here (at least, I'm confused), so let  
me see if I have this right:

1) Kumar is advocating the eventual removal of support for booting  
the 85xx CDS and 85xx ADS boards without a flat-device tree

2) Eugene and Dan say this will break systems that are already deployed

3) Kumar says that the 85xx CDS and ADS systems are reference  
platforms, and therefore not meant for deployment.

4) Eugene implies that removal of 85xx CDS and ADS support from arch/ 
ppc should be accompanied by some sort of compatibility options for  
booting arch/powerpc Linux from an old u-boot

Do I have this right?

Oh, and 5) Kumar implies that anyone who buys a repackaged CDS system  
is a sucker, and should be parted from his or her money with all  
possible speed.  :)
