b4b165112c PeripheryErrorSlave: do not put a TLMonitor between the fragmenter and slave 
This edge has the largest number of source bits by far. Let's just exclude it.

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.
