631e3e2dd9 Make PRCI a singleton, not per-tile 
Some stuff is densely packed in the address space (e.g. IPI regs),
so needs to be on the same TileLink slave port

20e1de08da Avoid chisel2 pitfall 
This code is erroneously flagged as incompatible with chisel3.
In fact, it is correct in both chisel2 and chisel3.  D'oh.

11b3cee07a Ahb tweaks (#50) 
* ahb: handle tlDataBytes==1 and tlDataBeats==1 gracefully

I only now learned that chisel does not handle 0-width wires properly
and that log2Up and log2Ceil differ on 1. Fix-up code to handle this.

* ahb: optionally disable atomics => optimize to nothing

Trust the compiler the compiler to optimize away unused logic.

3cc236e9c4 By default, use same TileLink width everywhere 
When there's no L2 with a wide interface, having wider TileLink
is only disadvantageous.
