Moving work back to zizzer...
configs/common/FSConfig.py:
configs/test/fs.py:
Move CPU connections out of makeLinuxAlphaSystem()
src/python/m5/objects/BaseCPU.py:
Create default TLBs in full system.
Move utility cache functions here.
src/python/m5/objects/O3CPU.py:
Add _mem_ports
tests/run.py:
Add binpath()
Change maxtick default to 'forever'
tests/simple-atomic.py:
Use connectmemPorts()
tests/simple-timing.py:
Fix up.
