Write test harness in Chisel This is an unavoidably invasive commit, because it affects the unit tests (which formerly exited using stop()), the test harness Verilog generator (since it is no longer necessary), and the DRAM model (since it is no longer connected). However, this should substantially reduce the effort of building test harnesses in the future, since manual or semi-automatic Verilog writing should no longer be necessary. Furthermore, there is now very little duplication of effort between the Verilator and VCS test harnesses. This commit removes support for DRAMsim, which is a bit of an unfortunate consequence. The main blocker is the lack of Verilog parameterization for BlackBox. It would be straightforward to revive DRAMsim once support for that feature is added to Chisel and FIRRTL. But that might not even be necessary, as we move towards synthesizable DRAM models and FAME-1 transformations.

Massive update containing several months of changes from the now-defunct private chip repo. * Adds support for a L2 cache with directory bits for tracking L1 coherence (DefaultL2Config), and new metadata-based coherence API. * Additional tests. * New virtual memory implementation, priviliged architecture (1.7), custom CSRs, FDivSqrt unit * Updated TileLink protocol, NASTI protocol SHIMs. * Lays groundwork for multiple top-level memory channels, superscalar fetch. * Bump all submodules.

$(MAKE) -C $(dir $@) $(notdir $@)
Support make-3.82 and newer make changed its priorties for resolving implicit rules, which causes different behavior when running "make run-bmark-tests". This patch changes the hex file rules to ensure they match between the two versions of make. I've tried this with both make-3.81 and make-4.1, and they both work for me.
