What is a "front side cache"?  What exactly does it cache?  If it's
a cache for one CPU only, that fact should be shown in the device
tree somehow.

Its in front of the memory controllers.  Its not specific to a  
given CPU.

Ah, I see.  That relationship is implicit in the device tree already,
both this cache controller and that memory controller are child nodes
of the same soc node, so your device tree is fine.

Just for my own understanding, is this a coherent cache?  (I'm too
lazy to read the manual ;-) )

yes its coherent.  Our caches tend to be coherent.
