Steve Reinhardt c8538d6a7e Enhancements to python config proxy class.
python/m5/config.py:
    - Enhanced Proxy class now supports subscripting, e.g.,
    parent.cpu[0] or even parent.cpu[0].icache.

    - Proxy also supports multiplication (e.g., parent.cycle * 3),
    though this feature has not been tested.

    - Subscript 0 works even on non-lists, so you can safely say
    cpu[0] and get the first cpu even if there's only one.

    - Changed name of proxy object from 'Super' to 'parent', and
    changed "wild card" notation from plain 'Super' to 'parent.any'.

#
# The real solution to this problem is to pass the ParamXXX structure
# to the constructor, but with the express condition that SimObject
# parameter values are not to be available at construction time. If
# some further configuration must be done, it must be done during the
# initialization phase at which point all SimObject pointers will be
# valid.
