Wesley W. Terpstra 18b8a61775 Error device: require explicit control of atomic and transfer sizes 2017-12-08 13:41:09 -08:00
Wesley W. Terpstra 8781d2b2e7 diplomacy: provide a val name for all LazyModule constructions 2017-12-01 11:28:21 -08:00
Wesley W. Terpstra e489c4226e diplomacy: remove node arity and allow empty Nexus nodes (Xbars) 
This removes the mostly obsolete 'numIn/Out' range restrictions on nodes.
It also makes it possible to connect optional crossbars that disappear.

val x = TLXbar()
x := master
slave := x

val y = TLXbar()
x :=* y // only connect y if it gets used

This will create crossbar x, but crossbar y will disappear.

Wesley W. Terpstra fbbfc9c096 diplomacy: include edge type in inward/outward node handles 
This is necessary capture the node implementation in the handle,
which is in turn necessary to support cloning a Node.

Wesley W. Terpstra 45a904b396 ahb: ignore hrdata on an AHB error 
From the AHB spec:
 "A slave only has to provide valid data when a transfer completes with an OKAY
  response. ERROR responses do not require valid read data."

Wesley W. Terpstra 8b58327fa4 axi4: conversion from TL does not need beatBytes (#1051) 
We used to pack the addr_lo into user bits. We don't do that anymore.
There is thus no need to waste those bits, nor to pass that arg.

Henry Cook 01ca3efc2b Combine Coreplex and System Module Hierarchies (#875) 
* coreplex collapse: peripherals now in coreplex

* coreplex: better factoring of TLBusWrapper attachement points

* diplomacy: allow monitorless :*= and :=*

* rocket: don't connect monitors to tile tim slave ports

* rename chip package to system

* coreplex: only sbus has a splitter

* TLFragmenter: Continuing my spot battles on requires without explanatory strings

* pbus: toFixedWidthSingleBeatSlave

* tilelink: more verbose requires

* use the new system package for regression

* sbus: add more explicit FIFO attachment points

* delete leftover top-level utils

* cleanup ResetVector and RTC
