ad93e0226d Changes to prepare for switch to TileLink interconnect
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.

* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect

39cf945efb Use Chisel 3 to build verilog on Travis
Chisel 3 can't build the C++ emulator, so we currently can't have direct
support for testing RocketChip.  We can at least test to see if the
Verilog builds when run through Chisel 3, which this patch does.

cddfdf0929 Add CHISEL_VERSION make argument
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.

6da45e7f26 Trace generator: updates and additions to the scripts directory.
(1) Introduce tracegen.py, a script that invokes the emulator (built
    with TraceGenConfig), sending a SIGTERM once all cores are finished.

(2) Update toaxe.py to gather some statistics about the trace.

(3) Introduce tracestats.py, which displays the stats in a useful way.

(4) Introduce tracegen+check.py, a top-level script that generates
    traces, checks them, and emits stats.  If this commit is pulled, it
    should be done after pulling my latest groundtest commit.

Fix the backup memory port

a0f3189c74 Change MIF_DATA_BITS back to 64
It turns out the Chisel C++ backend can't emit correct initialization
code for a 128 bit wide NastiROM.  Rather than trying to fix Chisel, I'm
just going to hack up the backup memory port Verilog harness a bit more
to make it work.

Note that the backup memory port Verilog already couldn't take arbitrary
parameters for MIF_*, so it's not like we're losing any flexibility
here.

7319f430d0 Fix the backup memory port on multiple-channel configs
The backup memory port doesn't work on multi-channel configurations, it
just screws up the Nasti tag bits.  This patch always instantiates a
single-channel backup memory port, which relies on the memory channel
selector to only enable a single memory channel when the backup memory
port is enabled.  There are some assertions to make sure this happens,
as otherwise memory gets silently corrupted.

While this is a bit of a hack, the backup memory port will be going away
soon so I don't want to spend a whole lot of time fixing it.  The
generated hardware is actually very similar: we used to elaborate a
Nasti arbiter inside the backup memory support, now there's one outside
of it instead.

7c0c48fac4 Resurrect the backup memory port
We need this to work for our chip, and it's not been tested in a long
time in upstream -- it didn't even used to build since the Nasti
conversion.  This makes a few changes:

 * Rather than calling the backup memory port parameters MEM_*, it calls
   them MIF_* (to match the MIT* paramater objects).  A new name was
   necessary because the Nasti stuff is now dumped as MEM_*, which has
   similar names but incompatible values.

 * p(MIFDataBits) was changed back to 128, as otherwise the backup
   memory port doesn't work (it only send half a TileLink transaction).
   64 also causes readmemh to bail out, but changing the elf2hex parameters
   works around that.

 * A configuration was added that enabled the backup memory port in the
   tester.  While this is kind of an awkward way to do it, I want to
   make sure I can start testing this regularly and this makes it easy to
   integrate.
