TimingSimpleCPU, which use atomic and timing memory accesses
respectively. Common code is factored into the BaseSimpleCPU class.
AtomicSimpleCPU includes an option (simulate_stalls) to add delays
based on the estimated latency reported by the atomic accesses.
Plain old "SimpleCPU" is gone; I have not updated all the config
files (just test/test.py).
Also fixes to get timing accesses working in new memory model and
to get split-phase memory instruction definitions working with
new memory model as well.
arch/alpha/isa/main.isa:
Need to include packet_impl.h for functions that use Packet objects.
arch/alpha/isa/mem.isa:
Change completeAcc() methods to take Packet object pointers.
Also split out StoreCond template for completeAcc(), since
that's the only one that needs write_result and we get an
unused variable warning if we always have it in there.
build/SConstruct:
Update list of recognized CPU model names.
configs/test/test.py:
Change SimpleCPU to AtomicSimpleCPU.
cpu/SConscript:
Define sources for new CPU models.
Add split memory access methods to CPU model signatures.
cpu/cpu_models.py:
cpu/static_inst.hh:
Define new CPU models.
cpu/simple/base.cc:
cpu/simple/base.hh:
Factor out pieces specific to Atomic or Timing models.
mem/bus.cc:
Bus needs to be able to route timing packets based on explicit dest
so responses can get back to requester. Set dest to Packet::Broadcast
to indicate that dest should be derived from address.
Also set packet src field based on port from which packet is sent.
mem/bus.hh:
Set packet src field based on port from which packet is sent.
mem/packet.hh:
Define Broadcast destination address to indicate that
packet should be routed based on address.
mem/physical.cc:
Set packet dest on response so packet is routed
back to requester properly.
mem/port.cc:
Flag blob packets as Broadcast.
python/m5/objects/PhysicalMemory.py:
Change default latency to be 1 cycle.

CPU_MODELS parameter. For example:
scons CPU_MODELS="SimpleCPU,FullCPU" ALPHA_SE/m5.debug
Unfortunately the option is not sticky due to a scons
bug with saving & restoring ListOption parameters.
SConscript:
Separate out cpu-model-specific files so they can be conditionally
included based on value of new CPU_MODELS parameter.
Most of these are now handled in cpu/SConscript, except for FullCPU
which is still in this file.
arch/SConscript:
The set of CPU-model-specific execute files must now be
determined from the CPU_MODELS parameter, via the new
cpu_models.py file.
Also pass the list of configured CPU models to isa_parser.py.
arch/isa_parser.py:
Move CpuModel definition and objects out to a
separate file so they can be shared with scons.
Global list of CPU models to generate code for is now
controlled by command-line parameters (so we can do
only a subset of the available ones).
build/SConstruct:
Define new CPU_MODELS ListOption.
cpu/static_inst.hh:
Rename static_inst_impl.hh to static_inst_exec_sigs.hh.
