67467c65f5 Add a jtag-dtm-regression target to the regression
This doesn't get added to Travis, but this target can be used
by other automated testing tools which may want to do further
testing on rocket-chip.

3dd51ff734 This commit adds Logic & test support for JTAG implementation of Debug Transport Module.
- The DebugTransportModuleJtag is written in Verilog. It probably could be written in
  Chisel except for some negative edge clocking requirement.
- For real implementations, the AsyncDebugBusTo/From is insufficient. This commit
  includes cases where they are used, but because they are not reset asynchronously,
  a Verilog 'AsyncMailbox' is used when p(AsyncDebug) is false.
- This commit differs significantly from the earlier attempt. Now, the
  DTM and synchronizer is instantiated within Top, as it is a real piece of
  hardware (vs. test infrastructure).
-TestHarness takes a parameter vs. creating an entirely new TestHarness class.
It does not make sense to instantiate TestHarness when p(IncludeJtagDTM) is false,
and it would not make sense to insantiate some other TestHarness if p(IncludeJtagDTM)
is true.

To build Verilog which includes the JtagDTM within Top:

make CONFIG=WithJtagDTM_...

To test using gdb->OpenOCD->jtag_vpi->Verilog:

First, install openocd (included in this commit)

./bootstrap
./configure --prefix=$OPENOCD --enable-jtag-vpi
make
make install

Then to run a simulation:

On a 32-bit core:

$(ROCKETCHIP)/riscv-tools/riscv-tests/debug/gdbserver.py \
  --run ./simv-TestHarness-WithJtagDTM_... \
  --cmd="$OPENOCD/bin/openocd --s $OPENOCD/share/openocd/scripts/" \
  --freedom-e300-sim \
  SimpleRegisterTest.test_s0

On a 64-bit core:

$(ROCKETCHIP)/riscv-tools/riscv-tests/debug/gdbserver.py \
  --run ./simv-TestHarness-WithJtagDTM_... \
  --cmd="$OPENOCD/bin/openocd --s $OPENOCD/share/openocd/scripts/" \
  --freedom-u500-sim \
  SimpleRegisterTest.test_s0

3f8c60bbd6 Hierarchicalize FPU and MulDiv parameters
This gets some leaf-level parameters out of the global parameterization,
better separating concerns.  This commit also allows disabling the
M extension.

fee5d2b1ea Remove parameters for some things that aren't parameterizable
Heads up @colinschmidt and @ccelio.  I'm removing these because
they are ISA constants and so are not truly parameters, so the
parameter place is not the place for them.  Since BOOM and Hwacha
both depend on rocket, you should be able to obtain them by
instantiating/extending rocket.HasCoreParameters.

The registers can still hold invalid values, but an attempt to switch
to the mode stored therein will instead go to an implemented mode.
