63679bb019 Add support for L1 data scratchpads instead of caches
They fit in the same part of the address space as DRAM would be, and
are coherent (because they are not cacheable).

They are currently limited to single cores without DRAM.  We intend
to lift both restrictions, probably when we add support for
heterogeneous tiles.

dc9ae19936 Work-around for current Scala compiler "structural type loses implicits".
Running rocket-chip through the chisel3 gsdt branch which supports stricter connection checks and uses implicit definitions to deal with "old" direction overrides, exposed a possible bug in the Scala compiler.

    [error] .../src/main/scala/uncore/devices/Prci.scala:27: value asOutput is not a member of uncore.devices.PRCIInterrupts{val mtip: chisel3.core.Bool; val msip: chisel3.core.Bool}
    [error] possible cause: maybe a semicolon is missing before `value asOutput'?
    [error]   }.asOutput
    [error]     ^
    [error] one error found
    [error] (uncore/compile:compileIncremental) Compilation failed

This change isn't strictly required for current chisel3 code, but is being submitted in anticipation of an eventual merge of the gsdt branch prior to a compiler fix.

c05ba1e864 Add TileId parameter, generalizing GroundTestId
This usually shouldn't be used in Tiles that are meant to be P&R'd once
and multiply instantiated, as their RTL would no longer be homogeneous.
However, it is useful for conditionalizing RTL generation for
heterogeneous tiles.

07d48df88a Get rid of FPU RoCC port logic when RoCC not present
The previous approach used ex_reg_valid to determine whether to
source data from the FPU or RoCC.  Thus, when the RoCC was not
present, it was still creating muxes.  Using ex_cp_valid instead
gets rid of them.

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/" \

ed827678ac 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.
