PhysicalMemory has vector of uniform ports instead of one special one.
configs/example/memtest.py: PhysicalMemory has vector of uniform ports instead of one special one. Other updates to fix obsolete brokenness. src/mem/physical.cc: src/mem/physical.hh: src/python/m5/objects/PhysicalMemory.py: Have vector of uniform ports instead of one special one. src/python/swig/pyobject.cc: Add comment. --HG-- extra : convert_revision : a4a764dcdcd9720bcd07c979d0ece311fc8cb4f1
