Changeset 11798:3a490c57058d

---------------------------

misc: Clean up and complete the gem5<->SystemC-TLM bridge [5/10]
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:

 * Introduce transactor modules that represent the gem5 ports in the SystemC

   world.

 * Update the SimControl module and let it keep track of the gem5 ports.
