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: * Move common code of the example to a common directory. Move the cli * parsing from the SimControl module to a separate example object. Add * comments describing the Gem5SimControl module. Testing Done: Examples compile and run. Reviewed at http://reviews.gem5.org/r/3695/ Signed-off-by: Jason Lowe-Power <jason@lowepower.com>
