description:
misc: Clean up and complete the gem5<->SystemC-TLM bridge [10/10]
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:
* Add callbacks for the Gem5SimControl that are called at before and
* after simulate()
