e928b741ce Default mtvec=0, not None 
Setting it to None was a mistake.  It makes it far harder to
diagnose boot bugs, as you end up fetching from random addreses
after trapping.

c45cc76cef Get rid of remaining MemIO code 
The only thing we were still using it for was for the MIFDataBits
and MIFTagBits parameters. We replace these with EdgeDataBits and
EdgeIDBits.

7d6fb950b6 Give TileLink IDs more sensible names 
* Outermost -> MCtoEdge
 * MMIO_Outermost -> MMIOtoEdge

Then the corresponding parameters objects are

 * L1toL2 -> innerParams
 * L2toMC -> outerMemParams
 * L2toMMIO -> outerMMIOParams
 * MCtoEdge -> edgeMemParams
 * MMIOtoEdge -> edgeMMIOParams

201e247f73 Factor coreplex IO connection into separate trait (#350) 
This would allow, for instance, putting the coreplex on a separate clock
domain and crossing the IOs over through asynchronous queues.

The ExampleMultiClockTop* classes are removed since they no longer fit
into the class hierarchy.

ea9f0a868f TileLink utility objects should not take implicit parameters 
We have a handful of TileLink-related helper objects
(wrappers, unwrappers, width adapters, and enqueuers). Previously, using
them could be error-prone, because you had to make sure the implicit
parameters they took in had the same TLId as the TileLinkIO bundles
passed in as inputs. This is rather silly, we should just use the
parameters in the bundle.

d0572d6aab Allow reset vector to be set dynamically 
A chip's power-up sequence, or awake-from-sleep sequence, may wish to
set the reset PC based upon dynamic properties, e.g., the settings of
external pins.  Support this by passing the reset vector to the Coreplex.
ExampleTop simply hard-wires the reset vector, as was the case before.

Additionally, allow MTVEC to *not* be reset.  In most cases, including
riscv-tests, pk, and bbl, overriding MTVEC is one of the first things
that the boot sequence does.  So the reset value is superfluous.

61cbe6164d Add option to execute JAL from decode stage 
This is particularly helpful for designs that don't have a BTB, but
it becomes the critical path for designs with RVC.  Caveat emptor.

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.
