b2ed35e8aa Print a better error on missing config classes 
Without this you don't actually see what config class you tried to use, which
makes it hard to grep around Makefiles to see why things are broken.

8422aaf6fc Add a "/" when targetDir doesn't have one 
This isn't Chisel 3 specific, but that's what I happened to do in the Chisel 3
Driver wrapper.

62257e0b04 Uncomment MemSerializedIO.cloneType() 
Not sure why this was commented, but when I build this against Chisel3 it fails
without this override.

be424633c1 Improve ParamaterizedBundle.cloneType()'s error messages 
Without this it's really hard to read the IllegalArgumentException that you get
if you subclass ParamaterizedBundle and don't define a matching cloneType().

06c3f9b655 Rocket Chip fixes in response to lowRISC team's comments 
* DMA frontend-backend communication tunneled over TileLink/AXI
 * Split MMIO and Mem requests in l1tol2net instead of in AXI interconnect
 * Don't make NIOMSHRs configurable. Fixed at 1.
 * Connect accelerator-internal CSRs into the CSR file
 * Make mtvec register configurable and writeable

bfdf5a538a Separate memory interconnect from IO interconnect. 
Since we're separating memory and MMIO traffic in the L1 to L2 network,
we won't need to route between memory and MMIO at the AXI interconnect.
This means we can have separate (and simpler) AXI interconnects for
each. One consequence of this is that the starting address of the IO
interconnect can no longer be assumed to be 0 by default.

e18759642f Avoid running Chisel in parallel in the same directory 
It looks like Chisel fails when I try to run it in parallel.  This adds a lock
file to ensure that only a single Chisel instance is running at a time when
running the regressions.

Since the latest Spike fix my torture runs are succeeding, so I can now run it
as part of the regression flow.

1149a412cc Support make-3.82 and newer 
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.

7209c13338 Move to a regression Makefile 
In order to have the buildbot support various types of failures it needs
to run different commands.  Rather than modifying the regression script
to have a bunch of arguments I've just gone and made a makefile for
regressions instead.

This doesn't run torture right now because that's broken, but I'll add
support soon.
