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.

91d1880dbf ClockDivider2: fix launch alignment of clocks (vcs) 
Doing this in Chisel leads to non-determinism due to shitty
Verilog ordering semantis. Using an '=' ensures that all of
the clock posedges fire before concurrent register updates.

See "Gotcha 29: Sequential logic that requires blocking assignments"
in "Verilog and SystemVerilog Gotchas" by Stuart Sutherland, Don Mills.

77a0f76289 Cleanup jtag dtm (#342) 
* debug: Clean up Debug TransportModule synchronizer

With async reset async queues, I feel its safe/cleaner
to remove the one-off "AsyncMailbox verilog black-box
and use the common primitive.

I also added some comments about correct usage of this
block. Probably the 'TRST' signal should be renamed
to make it less confusing, as it requires some processing
of the real JTAG 'TRST' signal.

a031686763 util: Do BlackBox Async Set/Reset Registers more properly (#305) 
* util: Do Set/Reset Async Registers more properly

The way BlackBox "init" registers were coded before was
not really kosher verilog for most synthesis tools.
Also, the enable logic wasn't really pushed down into the flop.

This change is more explicit about set/reset flops,
again this is only a 'temporary' problem that would go away
with parameterizable blackboxes (or general async reset support).

* Tabs, not spaces, in Makefiles

* util: Fix typos in Async BB Reg Comments
