Instead of just passing a list of controllers to the makeTopology function in src/mem/ruby/network/topologies/<Topo>.py we pass in a function pointer which knows how to make the topology, possibly with some extra state set in the configs/ruby/<protocol>.py file. Thus, we can move all of the files from network/topologies to configs/topologies. A new class BaseTopology is added which all topologies in configs/topologies must inheirit from and follow its API. --HG-- rename : src/mem/ruby/network/topologies/Crossbar.py => configs/topologies/Crossbar.py rename : src/mem/ruby/network/topologies/Mesh.py => configs/topologies/Mesh.py rename : src/mem/ruby/network/topologies/MeshDirCorners.py => configs/topologies/MeshDirCorners.py rename : src/mem/ruby/network/topologies/Pt2Pt.py => configs/topologies/Pt2Pt.py rename : src/mem/ruby/network/topologies/Torus.py => configs/topologies/Torus.py
