63563c9df2 O3, Ruby: Forward invalidations from Ruby to O3 CPU
This patch implements the functionality for forwarding invalidations and
replacements from the L1 cache of the Ruby memory system to the O3 CPU. The
implementation adds a list of ports to RubyPort. Whenever a replacement or an
invalidation is performed, the L1 cache forwards this to all the ports, which
is the LSQ in case of the O3 CPU.

00ad4eb8ce Ruby: Fix instantiations of DMA controller and sequencer
The patch on Ruby functional accesses made changes to the process of
instantiating controllers and sequencers. The DMA controller and
sequencer was not updated, hence this patch.

c86f849d5a Ruby: Add support for functional accesses
This patch rpovides functional access support in Ruby. Currently only
the M5Port of RubyPort supports functional accesses. The support for
functional through the PioPort will be added as a separate patch.

8a652f9871 config: tweak ruby configs to clean up hierarchy
Re-enabling implicit parenting (see previous patch) causes current
Ruby config scripts to create some strange hierarchies and generate
several warnings.  This patch makes three general changes to address
these issues.

1. The order of object creation in the ruby config files makes the L1
   caches children of the sequencer rather than the controller; these
   config ciles are rewritten to assign the L1 caches to the
   controller first.

2. The assignment of the sequencer list to system.ruby.cpu_ruby_ports
   causes the sequencers to be children of system.ruby, generating
   warnings because they are already parented to their respective
   controllers.  Changing this attribute to _cpu_ruby_ports fixes this
   because the leading underscore means this is now treated as a plain
   Python attribute rather than a child assignment. As a result, the
   configuration hierarchy changes such that, e.g.,
   system.ruby.cpu_ruby_ports0 becomes system.l1_cntrl0.sequencer.

3. In the topology classes, the routers become children of some random
   internal link node rather than direct children of the topology.
   The topology classes are rewritten to assign the routers to the
   topology object first.

40bcbf4253 network: convert links & switches to first class C++ SimObjects
This patch converts links and switches from second class simobjects that were
virtually ignored by the networks (both simple and Garnet) to first class
simobjects that directly correspond to c++ ojbects manipulated by the
topology and network classes.  This is especially true for Garnet, where the
links and switches directly correspond to specific C++ objects.

By making this change, many aspects of the Topology class were simplified.

808701a10c memtest: Memtester support for DMA
This patch adds DMA testing to the Memtester and is inherits many changes from
Polina's old tester_dma_extension patch.  Since Ruby does not work in atomic
mode, the atomic mode options are removed.

10e25cb1d0 config: Improve ruby simobject names
This patch attaches ruby objects to the system before the topology is
created so that their simobject names read their meaningful variable
names instead of their topology name.
