e7f442d527 Simple program runs with sendAtomic!
Ignoring returned latency for now.
Refactored loadSections in ObjectFile hierarchy.

base/loader/aout_object.cc:
base/loader/aout_object.hh:
base/loader/ecoff_object.cc:
base/loader/ecoff_object.hh:
base/loader/elf_object.cc:
base/loader/elf_object.hh:
base/loader/object_file.hh:
    Have each section record a pointer to image data.
    This allows us to move common loadSections code into ObjectFile.
base/loader/object_file.cc:
    Have each section record a pointer to image data.
    This allows us to move common loadSections code into ObjectFile.
    Also explicitly load BSS now since we need to allocate the
    translations for it in syscall emulation.
cpu/base.hh:
    Don't need memPort (just pass port in to ExecContext constructor).
cpu/exec_context.cc:
cpu/exec_context.hh:
mem/port.cc:
mem/translating_port.cc:
mem/translating_port.hh:
    Pass syscall emulation Port into constructor instead of
    getting it from BaseCPU.
cpu/simple/cpu.cc:
    Explicitly choose one of three timing models.
    Statically allocate request and packet objects when possible.
    Several more minor bug fixes.
    Works for simple program with SIMPLE_CPU_MEM_IMMEDIATE model now.
    Probably have memory leaks with SIMPLE_CPU_MEM_TIMING (if it works at all).
    Pass syscall emulation Port into constructor instead of
    getting it from BaseCPU.
cpu/simple/cpu.hh:
    Explicitly choose one of three timing models.
    Statically allocate request and packet objects when possible.
    Pass syscall emulation Port into constructor instead of
    getting it from BaseCPU.
mem/physical.cc:
    Set packet result field.

8fc06589cb Update functional memory to have a response event
Clean out old memory python files, move them into old_mem directory.  Maybe we should just delete them, they are under revision control.

Add new py files for new objects.

SConscript:
    Update because memory is just a header file now
base/chunk_generator.hh:
    Make Chunk Generator return the entire size if the chunk_size is set to zero.  Useful when trying to chunck on blocksize of memory, which can write large pieces of data.
cpu/simple/cpu.cc:
    Make sure to delete the pkt.
mem/physical.cc:
mem/physical.hh:
    Set up response event.
mem/port.cc:
    Rename rqst to req to conform to same standard naming convention.
python/m5/objects/PhysicalMemory.py:
    Update the params, inheritence

00264ff1b8 Rename port methods:
sendBlockSizeQuery() -> peerBlockSize()
recvBlockSizeQuery() -> deviceBlockSize()
After seeing how this gets used in practice, the
send/recv*Query names just don't make a lot of sense.

dev/io_device.cc:
mem/port.cc:
    sendBlockSizeQuery() -> peerBlockSize()
mem/port.hh:
    sendBlockSizeQuery() -> peerBlockSize()
    recvBlockSizeQuery() -> deviceBlockSize()

8a753f6ae2 Move read/writeBlob functions to Port class;
clean up implementation a little.

SConscript:
    Add mem/port.cc
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Move read/writeBlob functions to base Port class.
mem/port.hh:
    Implement read/writeBlob functions.
    No need for them to be virtual since the proxy
    object (now called TranslatingPort) is not a
    subclass of Port.
mem/port.cc:
    Implement read/writeBlob functions.
