1f8c4ba4ca CoreplexNetwork: don't force a buffer on the coherence manager
Let the l2Config.coherenceManager create its own appropriate buffers.
This can matter if you need to make sure the buffer is in the right
place in the hierarchy for hierarchical place and route.

Cake pattern only 2 layers instead of 3.
Standardized naming convention.
Comments for periphery mix-ins.
Testharnesses use new periphery helper methods.

76af15a6ff Fix FPU control bug for div/sqrt
I was examining a WB-stage control signal instead of a MEM-stage control
signal.  I refactored the code to group the signals together, so that this
sort of bug is less likely going forward.

87a5665e43 axi4: only block writes if SAME master has outstanding reads (#782)
* axi4: only block writes if SAME master has outstanding reads
* tilelink2: ToAXI4 rename variable
TL uses sources, not IDs like AXI. Keep it less confusing.
* tilelink2: ToAXI4 improve stall circuit delay
Don't bother decoding the AXI ID to compute stall.
