DMA Endpoint Mix-ins and some package reshuffling #110

Closed davidbiancolin closed 5 years ago

davidbiancolin commented 5 years ago

This PR does three things, to pave the way for print & trace synthesis.

1) Makes Widget extend MultiIOModule (yay!) 2) It takes the DMA-side hardware (BRAM-hosted queues) and moves them into mixins that be added to a Widget 3) Reorganizes the file structure in midas.widget into something more sensible

Endpoint and EndpointWidget are put in the widget/Endpoints.scala from core/Endpoints.scala
widget/NastiIO.scala only contains AXI-4 related endpoint code
DMA related code is moved into widget/DMATransport.scala
