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.
This allows users to specify if they want to build RocketChip against
Chisel 2 or 3. Since Chisel 3 is now open source we can add these
submodule pointers directly to avoid a fork of upstream.
This uses the new SCRFile changes to generate a header file containing a list
of all the SCRs in a core to remove the magic constant "63" (the HTIF clock
divider control register) and replace it with a generated number (which is
still 63).
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.
