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 --HG-- extra : convert_revision : bbbd8a56134f2dda2728091f740e2f7119b0c4af
