Add specific model numbers does not seem necessary because they are not 
needed to be specified in the device tree for compatible purposes for 
the kernel to work.  Plus, the list of model numbers will continue to 
grow over time and compatible strings would need to be added to the 
kernel for no apparent reason?

Thanks - removed specific boards from file and moved the cygnus.txt file 
to devicetree/bindings/arm/bcm/cygnus.txt in next version.  This seems 
to be like the appropriate place to put this document. We will need to 
add back in board specific bindings when ALSA support is added.  But 
that will be a later commit to deal with.
