bb3f514e8d now able to add periphery devices through traits
Unfortunately, I had to touch a lot of code, which weren't quite possible to split up into multiple commits.
This commit gets rid of the "extra" infrastructure to add periphery devices into Top.

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.

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.

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
