The current TLM bridge only provides a Slave Port that allows the gem5 world to send request to the SystemC world. This patch series refractors and cleans up the existing code, and adds a Master Port that allows the SystemC world to send requests to the gem5 world. This patch: * Restructure the existing sources in preparation of the addition of the * new Master Port. * Refractor names to allow for distinction of the slave and master port. * Replace the Makefile by a SConstruct. Testing Done: The examples provided in util/tlm (now util/tlm/examples/slave_port) still compile and run error free.
