there.
Get rid of addPort().
Change getPort() behavior on PhysicalMemory.
SConscript:
cpu/simple/cpu.hh:
sim/system.cc:
sim/system.hh:
Replace Memory with MemObject.
cpu/base.hh:
No need to declare Port here anymore.
cpu/cpu_exec_context.hh:

cpu/simple/cpu.cc:
mem/physical.cc:
mem/physical.hh:
Replace Memory with MemObject.
Get rid of addPort(); allow getting anonymous ports with getPort().
mem/translating_port.hh:
Remove unneeded header.
sim/process.cc:
Replace Memory with MemObject.
Change how initialization port gets set up to deal with change in
addPort()/getPort(). Current solution is not ideal but it works.
sim/process.hh:
Remove unneeded headers and declarations.
Make LiveProcess::getDesc() abstract instead of panicing if called.
sim/syscall_emul.hh:
Fix includes.

- know nothing about Fault objects (as it should be)
- call fatal() by default on accesses to unmapped addrs
- provide "try" versions for callers that are prepared to handle failure
mem/translating_port.cc:
mem/translating_port.hh:
Memory system objects should not return Fault objects, just errors.
Half the time we don't check the return code anyway, so make
default version of the access functions call fatal().
Provide "try*" versions that return a bool for places where we
really are going to check the return code.
sim/syscall_emul.cc:
sim/syscall_emul.hh:
Need to use new "tryReadString" here since we actually check the return code.

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).
