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

d52117d1e3 add in serialization of AtomicSimpleCPU _status. This is needed because right now unserializing breaks an assert since CPU status is not saved. Kev says that this will break uniform serialization across CPUs since each type of CPU has its own "status" enum set. So, the repercussions are that if you serialize in this CPU, you must first unserialize in this CPU before switching to something else you want.

fe762278e7 Updates to bring MemTest closer to working with newmem. Ron still needs to do the initial setup and configuration for it to work properly.
