[casper] Migrating to Roach 2 from Roach 1

[Paul Davis]

We currently have a few Roach1's but we need to get more.  Is there any
reason to change to the Roach 2?  The Roach1 already does everything we
need so we don't need the increased capabilities.  Does the toolflow change
at all?  From what I can see I just need to recompile with a new device. Is
this true?
