This, with riscv-fesvr modifications, enables the rocket-chip emulator
to understand (and error out) if a command line argument that will
eventually be consumed by HTIF looks bad and can error out quickly.
This relies on modifications to risc-fesvr to support getopt and the
exposure of what HTIF arguments exist via the `htif.h` header.
This removes the necessary preprocessing of riscv-fesvr arguments to
avoid situations where riscv-fesvr thinks that an argument is the
binary. Support for this is rolled into riscv-fesvr.
Cleanups, and print out log names ASAP.
Factor out gdbserver common invocation into GDBSERVER (fixing
--print-failtures).
Add --print-log-names to that command so the logfiles can be inspected
while the simulation is still running.
`RISCV=... cmd` is more idiomatic than `export RISCV=... && cmd`
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.
* Make dts generation reusable across tile subclasses
* First attempt to standardize tile IO nodes and connect methods
* hartid => hartId when talking about scala Ints
HasTiles now deals with only extremely general tile IOs.
Some RocketTiles specific behavior moved into RocketCoreplex.
BaseTile now has optional LocalInterruptNode.

After detecting a corrupted BTB, don't speculatively update it until
the next non-speculative fetch. This prevents the frontend from replaying
forever.
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.
