a857b08c59 [rocket] compute D$ tag bits based upon # of arbiter ports 2016-08-09 14:40:48 -07:00

a43ad522dc add clock override to tile constructor (#42) 
useful to have upstream so that tape-outs can construct
rocket-chip to have cores on different clocks without
forking rocket

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.

52fc34a138 Chisel3: bulk connect is not commutative 
We haven't decided if this is a FIRRTL limitation that we should relax,
or a backwards incompatibility we're forced to live with.  Should make
for lively debate.
