Vec considered harmful; use isOneOf instead ( #64 )
...
Vec is heavyweight and really should only be used for I/O and
dynamic indexing. A recurring pattern in uncore is
Vec(const1, const2, const3) contains x
which is nice but has a deleterious effect on simulation copilation
and execution time. This patch proposes an alternative:
x isOneOf (const1, const2, const3)
x isOneOf seqOfThings
I think it's also more idiomatic.
This is just a prototype; I'm not wed to the name or implementation.

Nasti Puts: decode wmask to determine addr_byte() and op_size()

This change is TL0 specific; TL2 knows the op_size, and can use

Refactor the TransactionTracker logic in all the L2 TileLink Managers.
...
They now share common sub-transactions within traits, and use a common
set of state transitions and scoreboarding logic. Tracker allocation
logic has also been updated. No changes to external IOs or the TileLink protocol.
A new bufferless Broadcast hub is also included, but does not yet pass fuzzing checks.

Add a Smi to TileLink converter ( #59 )
...
I'm trying to get someone to attach their stuff to Rocket Chip for the
upcoming tapout. TileLink sounded too complicated, but Smi went over
well. Since the mmioNetwork in Rocket Chip is based on TileLink, it
seemed like the easiest thing to do was to write a TileLink to Smi
converter so people could use it.
It turns out there was already one inside the groundtest unit tests, so
I just moved that into uncore (it was inlined into a test case so you
couldn't actually use it before). Internally the converter uses Nasti,
but I figured that's good enough for now.
