33a05786db tilelink2 RAMModel: fix put, get, putAck, getAck case (#282) 
This case should result in undefined data for the Get.
It was previously requiring the Get to return the new Put data,
which is only guaranteed by a FIFO device.

61cbe6164d Add option to execute JAL from decode stage 
This is particularly helpful for designs that don't have a BTB, but
it becomes the critical path for designs with RVC.  Caveat emptor.

82681179cb [tilelink2] Edges: add size to addr_lo. 
addr_lo cannot correctly be deciphered from the mask alone.
OxC still has addr_lo === 0 if size is >1.

bb3f514e8d now able to add periphery devices through traits 
Unfortunately, I had to touch a lot of code, which weren't quite possible to split up into multiple commits.
This commit gets rid of the "extra" infrastructure to add periphery devices into Top.
