b403abfbdb Move the port from base memory object into the physical memory object.
The Memory is now a pure virtual base class for all memory type objects (DRAM, physical).
We should consider renaming MemObject to something more meaningful to represent it is for all memory heirarchy objects, perhaps MemHeirObject?

mem/physical.cc:
mem/physical.hh:
    Move the port from the base class into the actual object.

9c4e4a2181 Move op_class.hh out of encumbered/cpu/full and into cpu.
Pull opClassStrings array out of encumbered/cpu/full/fu_pool.cc and move to

    Add new cpu-model-independent file to define OpClass enum strings.

1fff9f504f Some more changes for compilation. Since memset is now part of port and not virtual, no need for memory to define them.
mem/physical.cc:
    Return 0 for block size.  The chunk generator should treat this as a infinite size.
mem/physical.hh:
    Add function prototype
mem/port.hh:
    Fix function to take no arguments
mem/translating_port.cc:
mem/translating_port.hh:
    Remove the memsetBlob because it doesn't exist yet.

4bd11c10a5 Add blocksize functions to physical memory. Fix the port we were using in the process loader.
mem/physical.cc:
    Implement the blockSize function, return VMPageSize for the physical memory
mem/port.hh:
    Add a function to get a pointer to a peer, needed for initVirtMem to work in the loader.
sim/process.cc:
    The way the translating port is setup we don't want the memory port, we want the peer port associated with that memory.  We may need to revisit this.

00be4e8510 Thanks to Ali, I was able to add chunk generation code in to handle a few cases. Still have some duplicated code we may want to revisit.
cpu/simple/cpu.cc:
    Thanks to Ali I found the chunk generator, although I still seem to be duplicating some code becuase the only difference between readBlob and writeBlob is the command in the packet.  Perhaps an access function with the command as a param would help with the duplication (sendBlob that takes a cmd (maybe).

b8a2d1e5c7 More progress toward compiling... partly by
fixing things, partly by ignoring CPU models
that don't currently compile.

SConscript:
    Split sources for fast, simple, and o3 CPU models into
    separate source lists.  For now none of these are included
    in the base source list, so you won't get any CPU models
    at all... but we still can't compile the other stuff so
    it's not an issue.

eabb0cfc78 Pushing current state. Need to fix compilation problems, have moved the SCONS script to build memory objects first.

0e79d188e1 Hacks to avoid compiling in old FullCPU model.
Needed in the interim until we port the old model over
to the new interface.  Long term we should have a cleaner

    Move old FullCPU source file list to separate full_cpu_sources
    list so we can choose to not include it in compile.

    Hack to avoid generating FullCPU execute files.

07948528fc Add PageTable code and SConscript fixes for new syscall emulation
memory model.  These changes really should have been part of the
previous changeset.

SConscript:
    Move System and PhysicalMemory sources from being full_system_sources
    to base_sources, since they are now used in syscall emulation also.
    Also add source files for PageTable and ProxyMemory objects.
    Actual source files for PhysicalMemory and ProxyMemory are not committed
    yet since they still need to be ported from old interface.

16bda9c03e Fix roundUp function template so explicit arg is not
needed in a few more cases.

base/intmath.hh:
    align arg to roundUp should be int, not template class
sim/process.cc:
sim/syscall_emul.hh:
    No need for explicit template arg now that roundUp is fixed.
