f7216daee0 Add a cache version of FS (should really make this an option in original)
Now to work on caches in FS, first steps:
1) LL/SC support (Top Level Cache Hooks)
2) Snooping in the bus (CSHR's for DMA Invalidates)

1ccfdb442f Timing cache works for hello world test.
Still need
1) detailed CPU (blocking ability in cache)
1a) Multiple outstanding requests (need to keep track of times for events)
2)Multi-level support

4)LL/SC support
5)Functional path needs to be correctly implemented (temporarily works without multiple outstanding requests (simple cpu))

src/cpu/simple/timing.cc:
    Temp hack because timing cpu doesn't export ports properly so single I/D cache communicates only through the Icache port.

8ae4f45bc4 Fixes for draining.
src/cpu/simple/timing.cc:
    Update for changed return values.
src/python/m5/__init__.py:
    Loop in order to make sure all objects are really drained.  Objects may become undrained as other objects become drained (e.g. a bus-bridge has a packet, while a bus is empty, and the first drain() will cause the bus-bridge to give the packet to the bus).

    The only case we know every object is actually drained is if they all return immediately that they are drained.

Remove most of pciconfigall, it now is a dumbdevice which gets it's address based on the bus it's supposed to respond for
Remove need for pci config space from platform, add registerPciDevice function to prevent more than one device from having same
bus:dev:func and interrupt
Remove pciconfigspace from pci devices, and py files
Add calcConfigAddr that returns address for config space based on bus/dev/function + offset

30c516d51c Support for draining, and the new method of switching out. Now switching out happens after the pipeline has been drained, deferring the three way handshake to the normal drain mechanism. The calls of switchOut() and takeOverFrom() both take action immediately.

8c547d80b1 Change the return value of drain. False means the object wasn't able to drain yet.
src/python/m5/config.py:
    Invert the return value.
src/sim/sim_object.cc:
    Invert the return value of drain.
src/sim/sim_object.hh:
    Change the return value of drain.
