Henry Cook 93773a4496 Refactor L2 transaction trackers to each be capable of processing Voluntary Writebacks.
To elide several races between reading and writing the metadata array for different types of transactions, all L2XactTrackers can now sink Voluntary Releases (writebacks from the L1 in the current implementation). These writebacks are merged with the ongoing transaction, and the merging tracker supplies an acknowledgment of the writeback in addition to its ongoing activities. This change involved another refactoring of the control logic for allocating new trackers and routing incoming Acquires and Releases. BroadcastHub uses the new routing logic, but still processes all voluntary releases through the VoluntaryReleaseTracker (not a problem because there are no metadata update races).

Uncore Library

This is the repository for uncore components assosciated with Rocket chip project. To uses these modules, include this repo as a git submodule within the your chip repository and add it as a project in your chip's build.scala. These components are only dependent on the ucb-bar/chisel repo, i.e.

lazy val uncore = project.dependsOn(chisel)

ScalaDoc for the uncore library is available here and an overview of the TileLink Protocol is available here, with associated CoherencePolicy documentation here.
