More progress toward actually running a program.
See configs/test.py for test config (using simple binary in my home directory on zizzer). base/chunk_generator.hh: Fix assertion for chunkSize == 0 (not a power of 2) base/intmath.hh: Fix roundDown to take integer alignments. cpu/base.cc: Register exec contexts regardless of state (not sure why this check was in here in the first place). mem/physical.cc: Add breaks to switch. python/m5/objects/BaseCPU.py: Default mem to Parent.any (e.g. get from System). python/m5/objects/Ethernet.py: python/m5/objects/Root.py: HierParams is gone. python/m5/objects/PhysicalMemory.py: mmu param is full-system only. sim/process.cc: Stack mapping request must be page-aligned and page-sized. Don't delete objFile object in create since we are counting on it being around for startup(). --HG-- extra : convert_revision : 90c43ee927e7d82a045d6e10302d965797d006f7
