Ron Dreslinski 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).
mem/translating_port.cc:
    Using the chunck generator to break it up to be in page size chunks

Ron Dreslinski 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.

Ron Dreslinski d96de69abc Add in a new translating port that allows syscalls to translate addresses via the page table before accessing the memory port.
Other compile issues cleaned up.

SConscript:
    Changes to compile the new Translating Port.
    Split out memtester and eio support, will rework them back in after first getting a simpleCPU to work
arch/alpha/alpha_linux_process.cc:
arch/alpha/alpha_tru64_process.cc:
sim/syscall_emul.cc:
sim/syscall_emul.hh:
    Changes to use the new translating Port.
cpu/exec_context.cc:
cpu/exec_context.hh:
    Create a translating port in each execution context.
sim/process.cc:
    Fix the way we do proxy memory
