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.

944646124e Rename Port address range functions... like the block size
functions, the send/recv*Query naming seems awkward.
Also create a typedef for AddrRangeList.

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.

562efe214c Adding some definitons for read/write blob/string. I need to locate te code stever wrote to break up address ranges into blk/page size chunks.
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Add read/write blob definitions, still need to break it up into blk size chunks (where was the code stever wrote for that?)
mem/physical.hh:
    Remove un-needed function (I think)
mem/port.hh:
    Default these virtual functions to panic unimplented
mem/translating_port.cc:
    Again handling read/write string properly.

    Need the stever code to break things into page size chunks yet
mem/translating_port.hh:
    Having trouble with the const declerator.  I will need to read how it works, for now it compiles if I remove it.

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.

    Also get rid of obsolete encumbered/mem file.
base/loader/aout_object.cc:
base/loader/aout_object.hh:

cpu/exec_context.cc:
sim/process.cc:
sim/system.cc:
sim/system.hh:
    FunctionalMemory -> Memory
cpu/pc_event.hh:
    Get rid of unused badpc.
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Move Port functions into .cc file.
mem/port.hh:
    Make recvAddressRangesQuery panic by default instead
    of being abstract... do CPUs need to implement this?
mem/request.hh:
    Add prefetch flags.
sim/syscall_emul.hh:
    Start to fix...

7f114ca419 Many changes that make the new mem system compile. Now to convert the rest of the tree to use the new mem system.
mem/mem_object.hh:
    Create constrtor so it compiles
mem/packet.hh:
    Fix typedefs so they compile, add in a few more headers for compilation
mem/page_table.cc:
    convert to new mem system so it compiles
mem/page_table.hh:
    fix it to the version that had asid support.  Make it compile in the new system
mem/physical.cc:
    Fix some compilation bugs
mem/physical.hh:
    Add a type that made compile fail
mem/port.hh:
    Fix a spelling error that messed up compilation
mem/request.hh:
    fix typedefs and forward declerations so it compiles

6c7fdb1be7 More include files, removing definition of SendResult whioch isn't needed anymore
cpu/simple/cpu.hh:
    Some needed includes
mem/port.hh:
    Now we removed the sendResult and replaced with void,tick,bool don't need it defined anymore

4875b33467 changed sendresult -> bool,tick,void as appropriate
first crack at io devices code
made CpuRequest that derives from Request

dev/io_device.cc:
dev/io_device.hh:
    first crack at the classes for Pio and Dma devices
dev/platform.hh:
    We are going to a system pointer to get info about the memory system
mem/bus.hh:
    changed sendresult -> bool,tick,void as appropriate
mem/port.hh:
    changed sendresult -> bool,tick,void as appropriate;
    removed the sendTiming(pkt,t) call since it is not really
    implementable in a generic fashion
mem/request.hh:
    pulled items from Request into CpuRequest

a1033448ea Inital split up of the header files for the new memory system. Still need to fill in some of the include files, and other data types. But this will be the starting point.
mem/bus.hh:
    Inital crack at a bus object that has ports.  Still need to clean up the include file issues.
mem/mem_object.hh:
    Decleration of a base memory object.  Derives from simobject and adds a function to get the port associated with the object.
mem/packet.hh:
    Inital crack at the packet decleration.  Still need to clean up the include file issues.
mem/port.hh:
    Inital crack at the port decleration.  Still need to clean up the include file issues.
mem/request.hh:
    Inital crack at the request decleration.  Still need to clean up the include file issues.
