figure out the block size from devices attached to the bus otherwise use a default block size when no devices that care are attached
configs/common/FSConfig.py:
src/mem/bridge.cc:
src/mem/bridge.hh:
src/python/m5/objects/Bridge.py:
fix partial writes with a functional memory hack
src/mem/bus.cc:
src/mem/bus.hh:
src/python/m5/objects/Bus.py:
figure out the block size from devices attached to the bus otherwise use a default block size when no devices that care are attached
src/mem/packet.cc:
fix WriteInvalidateResp to not be a request that needs a response since it isn't
src/mem/port.hh:
by default return 0 for deviceBlockSize instead of panicing. This makes finding the block size the bus should use easier
