137e244bda misc: SystemC Elastic Trace Player Example.
This patch adds an example configuration for elastic trace playing into the
SystemC world, similar to the already existing traffic generator example in
/util/tlm.

1051223318 misc: Separate stats file for SystemC-gem5 co-simulation
In previous versions of systemC-gem5 coupling statistics were not updated
for the systemc-gem5 simulation. systemC-gem5 simulation only need the
previously built config.ini file and normal gem5 simulation has to be run
once to generate config.ini file. Thus stats.txt inside the m5out folder is
redundant for systemC-gem5 simulation. A new stats file is now generated
with the all the statistics for systemC-gem5 simulation. This will also
resolve the stats issue in tlm-sysmtemC simulation.

1b46c175fc misc: Bugfix in TLM memInhibit Command
memInhibitAsserted() has been removed from packet.hh. This change has been
reflected in TLM based SystemC memory.
This patch also adds a number of panics asserting the SystemC memory only
sees requests it expects.

02881a7bf3 base: remove Trace::enabled flag
The DTRACE() macro tests both Trace::enabled and the specific flag. This
change uses the same administrative interface for enabling/disabling
tracing, but masks the SimpleFlags settings directly. This eliminates a
load for every DTRACE() test, e.g. DPRINTF.

1bb6a100ab misc: Bugfix in TLM integration regarding CleanEvict Command
The CleanEvict command was not considered in /util/tlm/sc_port.cc this could
lead to a simulator crash. This issue is solved by ignoring this special
command type.

8723b08dbf misc: Coupling gem5 with SystemC TLM2.0
Transaction Level Modeling (TLM2.0) is widely used in industry for creating
virtual platforms (IEEE 1666 SystemC). This patch contains a standard compliant
implementation of an external gem5 port, that enables the usage of gem5 as a
TLM initiator component in SystemC based virtual platforms. Both TLM coding
paradigms loosely timed (b_transport) and aproximately timed (nb_transport) are
supported.

Compared to the original patch a TLM memory manager was added. Furthermore, the
transaction object was removed and for each TLM payload a PacketPointer that
points to the original gem5 packet is added as an TLM extension.  For event
handling single events are now created.
