5eab6c4b41 Make the notion of a global event tick independent of the actual
CPU cycle ticks.  This allows the user to have CPUs of different
frequencies, and also allows frequencies and latencies that are
not evenly divisible by the CPU frequency.  For now, the CPU
frequency is still set to the global frequency, but soon, we'll
hopefully make the global frequency fixed at something like 1THz
and set all other frequencies independently.

arch/alpha/ev5.cc:
    The cycles counter is based on the current cpu cycle.
cpu/base_cpu.cc:
    frequency isn't the cpu parameter anymore, cycleTime is.
cpu/base_cpu.hh:
    frequency isn't the cpu parameter anymore, cycleTime is.
    create several public functions for getting the cpu frequency
    and the numbers of ticks for a given number of cycles, etc.
cpu/memtest/memtest.cc:
cpu/simple_cpu/simple_cpu.cc:
cpu/simple_cpu/simple_cpu.hh:
cpu/trace/trace_cpu.cc:
    Now that ticks aren't cpu cycles, fixup code to advance
    by the proper number of ticks.
cpu/memtest/memtest.hh:
cpu/trace/trace_cpu.hh:
    Provide a function to get the number of ticks for a given
    number of cycles.
dev/alpha_console.cc:
    Update for changes in the way that frequencies and latencies are
    accessed.  Move some stuff to init()
dev/alpha_console.hh:
    Need a pointer to the system and the cpu to get the frequency
    so we can pass the info to the console code.

dev/ide_disk.hh:
dev/ns_gige.cc:
dev/ns_gige.hh:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
dev/ide_disk.cc:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
    Add some extra debugging printfs
dev/platform.cc:
dev/sinic.cc:
dev/sinic.hh:
    outline the constructor and destructor
dev/platform.hh:
    outline the constructor and destructor.
    don't keep track of the interrupt frequency.  Only provide the
    accessor function.
dev/tsunami.cc:
dev/tsunami.hh:
    outline the constructor and destructor
    Don't set the interrupt frequency here.  Get it from the actual device
    that does the interrupting.
dev/tsunami_io.cc:
dev/tsunami_io.hh:
    Make the interrupt interval a configuration parameter.  (And convert
    the interval to the new latency/frequency stuff in the python)
kern/linux/linux_system.cc:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
    For now, we must get the boot cpu's frequency as a parameter
    since allowing the system to have a pointer to the boot cpu would
    cause a cycle.
kern/tru64/tru64_system.cc:
    For now, we must get the boot cpu's frequency as a parameter
    since allowing the system to have a pointer to the boot cpu would
    cause a cycle.
python/m5/config.py:
    Fix support for cycle_time relative latencies and frequencies.
    Add support for getting a NetworkBandwidth or a MemoryBandwidth.
python/m5/objects/BaseCPU.mpy:
    All CPUs now have a cycle_time.  The default is the global frequency,
    but it is now possible to set the global frequency to some large value
    (like 1THz) and set each CPU frequency independently.
python/m5/objects/BaseCache.mpy:
python/m5/objects/Ide.mpy:
    Make this a Latency parameter
python/m5/objects/BaseSystem.mpy:
    We need to pass the boot CPU's frequency to the system
python/m5/objects/Ethernet.mpy:
    Update parameter types to use latency and bandwidth types
python/m5/objects/Platform.mpy:
    this frequency isn't needed.  We get it from the clock interrupt.
python/m5/objects/Tsunami.mpy:
    The clock generator should hold the frequency
sim/eventq.hh:
    Need to remove this assertion because the writeback event
    queue is different from the CPU's event queue which can cause
    this assertion to fail.
sim/process.cc:
    Fix comment.
sim/system.hh:
    Struct member to hold the boot CPU's frequency.
sim/universe.cc:
    remove unneeded variable.

153130e558 First step in fixing up parameter handling. Clean up the
way ranges work, more fully support metric prefixes for all
integer types, and convert memory sized parameters to the
MemorySize type.

python/m5/config.py:
    - no more _Param and _ParamProxy stuff.  Use the names
    ParamBase and ParamFactory to hopefully make it clearer
    what we intend.
    - Get rid of RangeSize and the old Range class and more fully flesh
    out the Range class to deal with types of parameters and different
    kinds of ranges.
    - Call toInteger on the CheckedInt types so we can use metric prefixes
    in strings for all integers.
    - Get rid of the K, M, and G constants.  Use the proper type or call
    one of the functions in the convert package.
python/m5/convert.py:
    Simple way to deal with both floating point and integer strings.
python/m5/objects/BaseCache.mpy:
python/m5/objects/Ethernet.mpy:
    This is a MemorySize typed parameter

cf05fa476d stick all python stuff into a top level python directory.
create an m5 package in python/m5
move the objects package into the m5 package
move the m5config into the m5 package as config
leave both importers outside of the package.

SConscript:
sim/main.cc:
    move sim/pyconfig/* -> python
python/SConscript:
    m5config.py -> m5/config.py (now automatically embedded)
    objects -> python/m5/objects
    embed all python files in python/m5
python/m5/config.py:
    importer renamed mpy_importer
    move code to m5/__init__.py
test/genini.py:
    deal with new python organization
    keep track of paths we want to add and add them after parameters
    are parsed.
