This commit changes metric units (e.g. kB, MB, and GB) to binary units
(KiB, MiB, GiB) in various files. This PR covers files that were missed
by a previous PR that also made these changes.
This commit contains the rest of the base 2 vs base 10 cache/memory
size clarifications. It also changes the warning message to use
warn(). With these changes, the warning message should now no
longer show up during a fresh compilation of gem5.

Remove the line "For use for simulation and test purposes only" in files
were AMD is the only copyright holder listed in the header. This happens
to be the case for all files where this line exists, removing it
completely from gem5.

This patch is adding an extra parameter to the Ruby.create_system
function. The idea is to remove any assumption about cpu configuration
in the ruby scripts.
At the moment the scripts are assuming a flat list of cpu assigned
to the system object. Unfortunately this is not standardized, as
some systems might empoloy a different layout of cpus, like grouping
them in cluster objects.
With this patch we are allowing client scripts to provide the cpu list
as an extra argument
This has the extra benefit of removing the indexing hack
if len(system.cpu) == 1:
which was present in most scripts

Add a DMA thread tester to the Ruby GPU tester to test the DMA state
machine in the protocol. Currently creates a dummy DMA device to pass
through Ruby.py and scans for the DMA sequencers due to opaqueness of
Ruby.py.
DMA atomics not yet supported as there is no protocol that implements
atomic transitions in the DMA state machine file.
Example run command:
build/GCN3_X86/gem5.opt configs/example/ruby_gpu_random_test.py \
--test-length=1000

Python 2.7 used to return lists for operations such as map and range,
this has changed in Python 3. To make the configs Python 3 compliant,
add explicit conversions from iterators to lists where needed, replace
xrange with range, and fix changes to exec syntax.
This change doesn't fix import paths since that might require us to
restructure the configs slightly.

This patch breaks out the most basic configuration options into a set
of base options, to allow them to be used also by scripts that do not
involve any ISA, and thus no actual CPUs or devices.
The patch also fixes a few modules so that they can be imported in a
NULL build, and avoid dragging in FSConfig every time Options is
imported.
Continue along the same line as the recent patch that made the
Ruby-related config scripts Python packages and make also the
configs/common directory a package.
All affected config scripts are updated (hopefully).
Note that this change makes it apparent that the current organisation
and naming of the config directory and its subdirectories is rather
chaotic. We mix scripts that are directly invoked with scripts that
merely contain convenience functions. While it is not addressed in
this patch we should follow up with a re-organisation of the
config structure, and renaming of some of the packages.
This patch moves the addition of network options into the Ruby module
to avoid the regressions all having to add it explicitly. Doing this
exposes an issue in our current config system though, namely the fact
that addtoPath is relative to the Python script being executed. Since
both example and regression scripts use the Ruby module we would end
up with two different (relative) paths being added. Instead we take a
first step at turning the config modules into Python packages, simply
by adding a __init__.py in the configs/ruby, configs/topologies and
configs/network subdirectories.
As a result, we can now add the top-level configs directory to the
Python search path, and then use the package names in the various
modules. The example scripts are also updated, and the messy
path-deducing variations in the scripts are unified.
