c069e66056 Modify the RoCC interface to include status in the command queue. (#41)
This addresses a bug in which changes in mstatus could
propagate to RoCCs before their time. Existing RoCCs that use
the status port will need to be modified to match this change.

This addresses the first half of #40.

4af6313288 TraceGen: Lookup -> MuxLookup
A recent commit to tracegen.scala introduced a call to BitPat() which
seems to mess up the subsequent call to Lookup().  (This function
seems undocumented so I'm not sure what's going on.)  As a fix, I've
removed the call to BitPat() and replaced Lookup() with MuxLookup().

2f70136f90 Fix the Nasti to Smi Converter for single-word Nasti busses
There's a register that tracks what word within a Nasti transaction a
Smi response cooresponds to, since Smi itself doesn't have any
multi-word stuff.  This breaks the single-word Nasti to Smi converter
due to what's essentially a 0-width wire bug: it ends up doing something
like

  word_offset_into_nasti := nasti_address(3, 3)

when "word_offset_into_nasti" should really be a 0-bit register, but due
to some log2Up block size calculation logic it's actually a 1-bit
register.  Thus, this expression ends up grabbing a bit of the address,
which causes odd addresses to get buffered incorrectly.

My fix is to just special-case the "Nasti bus width is the same as Smi
bus width" case.
