This DT shouldn't ever be used, except when a new unidentified board 
appears. In that case, I believe the correct solution is to add support 
for that new board to U-Boot and the kernel, rather than add fall-backs. 
Prior to that being done, a user can always copy whichever DT they want 
into filename bcm2835-rpi-other.dts for temporary testing/development, 
if they have reason to believe their new model is compatible with 
something else. In general, I don't think we have any reason to believe 
that even this new minimal DT is guaranteed to be compatible with any 
possible future hardware, so it seems a little risky to ship this file 
in anticipation.
