f876bc2bf0 More fixes for functional accesses. It now makes the writeback memory leak to crash all configs.
Working on that now.

src/mem/cache/base_cache.cc:
    Keep a list of the responders so we can search them on functional accesses.
src/mem/cache/base_cache.hh:
    Properly put things on a list for responses so we can search the list.
    Also, be sure to check the outgoing ports lists on a functional access (factor some common code out there)
src/mem/cache/cache_impl.hh:
    Properly return when the first read hit on a functional access.
    Make sure to call to check the other ports list of packets before forwarding it out.

9a6e896d3b Big fix for functional access, where we forgot to copy the last byte on write intersections.
src/mem/packet.cc:
    Make sure to copy the whole data (we were one byte short)

    Fix for the proper semantics of fixPacket

cb172d0332 Get SPARC to the point that it starts running. Add ability to load the ROM bin files, cleanup lockstep printing a bit
Since we don't have a platform yet, you need to comment out the default responder stuff in Bus.py to make it work.

SConstruct:
    Add TARGET_ISA to the list of environment variables that end up in the build_env for python
configs/common/FSConfig.py:
    add a simple SPARC system to being testing with, you'll need to change makeLinuxAlphaSystem to makeSparcSystem in fs.py for now
src/SConscript:
    add a raw file object, at least until we get more info about how to compile openboot properly
src/arch/sparc/system.cc:
src/arch/sparc/system.hh:
    add parameters for ROM files (OBP/Reset/Hypervisor), a ROM, load files into ROM
src/base/loader/object_file.cc:
src/base/loader/object_file.hh:
    add option to try raw when nothing works
src/cpu/exetrace.cc:
    cleanup lockstep printing a little bit
src/cpu/m5legion_interface.h:
    change the instruction to be 32 bits because it is
src/mem/physical.cc:
    fix assert that doesn't work if memory starts somewhere above 0
src/python/m5/objects/BaseCPU.py:
    Add if statement to choose between sparc tlbs and alpha tlbs
src/python/m5/objects/System.py:
    Add a sparc system that sets the rom addresses correctly
src/python/m5/params.py:
    add the ability to add Addr() together
