12d0c00822 Fix mtime RegField handling 
RegField.bytes was unconditionally overwriting mtime, preventing it

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.

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
