e52d52ae99 Link PlusArg to emulator command line options 
- adds a mutable singleton (PlusArgArtefacts) to store information
  about Rocket PlusArgs
- adds methods to PlusArgArtefacts to emit C snippets that are
  consumed by emulator.cc for correct argument parsing and help text
  generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
  ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs

e82328336e Add in a SimJTAG to connect to OpenOCD's remote-bitbang interface. 
This is simpler than JTAGVPI and is supported better by Verilor.
It is also the same thing Spike uses.

000cde2f8a Make ErrorDevice UNCACHEABLE instead of UNCACHED 
...even though it still supports Acquire.  This avoids needing to flush
the D$ on FENCE.I because of the presence of the ErrorDevice.

ad0b9a0b1b Reduce cases in which FENCE.I must flush D$ 
Memory regions that are uncacheable or have get/put effects should not
reside in the D$, so there is no need to flush them.

Enforce physical-address canonicalization

Andrew Waterman
ee1a9485df Enforce physical-address canonicalization 
When xLen > paddrBits, enforce that physical addresses are zero-extended.
This works by checking that the _virtual_ address is _sign_-extended, then
checking that its sign is positive.

Andrew Waterman
a1ebe6da4d Prevent frontend deadlock fetching from uncacheable memory 
After detecting a corrupted BTB, don't speculatively update it until
the next non-speculative fetch.  This prevents the frontend from replaying
forever.

b8098d18be diplomacy: remove the :=? operator in favour of magic :*=* (#1139) 
The reason for the :=? operator was for when you have an adapter chain
whose direction of cardinality you could not know. We used explicit
directives to tell these compositions which way to go.

Unfortunately, that makes the API leaky. You think the chain of adapters
is just one adapter, but you have to use strange Cardinality scopes to
use it. That's just bad.

The new :*=* just automagically figures it out from the graph.
