Special mpy importer is gone; everything is just plain
Python now (funky, but straight-up).
May not completely work yet... generates identical ini
files for many configs/kernel settings, but I have yet
to run it against regressions. This commit is for my
own convenience and won't be pushed until more testing
is done.
python/m5/__init__.py:
Get rid of mpy_importer and param_types.
python/m5/config.py:
Major cleanup. We now have separate classes and
instances for SimObjects. Proxy handling and param
conversion significantly reorganized. No explicit
instantiation step anymore; we can dump an ini file
straight from the original tree.
Still needs more/better/truer comments.
test/genini.py:
Replace LoadMpyFile() with built-in execfile().
Export __main__.m5_build_env.
python/m5/objects/AlphaConsole.py:
python/m5/objects/AlphaFullCPU.py:
python/m5/objects/AlphaTLB.py:
python/m5/objects/BadDevice.py:
python/m5/objects/BaseCPU.py:

python/m5/objects/SimConsole.py:
python/m5/objects/SimpleDisk.py:
python/m5/objects/Tsunami.py:
python/m5/objects/Uart.py:
Fixes for eliminating mpy_importer, and modified
handling of frequency/latency params.
Also renamed parent to Parent.
