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.
