Let me catch the ball in flight here as the responsible folk was me.

For the transition to DT to be effective for new boards on ARM, I 
suggested that the machine registry would need to be closed at this 
point i.e. no new additions to it.  As far as I remember, Vincent 
volunteered to talk to you about it, which he apparently did within the 
same hour.  That's all there was to it.
