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
