2a348ccd6c python,scons: Add a dummy m5/objects/SimObject.py. 
This serves two purposes. First, it's a way to declare the base
SimObject class and params using the SimObject() SCons mechanism, while
the actual class still lives at m5/SimObject.py.

Second, it alleviates a very old inconsistency where *most* SimObjects
are imported using the m5.objects.Foo path, except SimObject itself
which lives under m5.SimObject. With this change, it will live under
both, more or less.

It may be possible to remove the inconsistency entirely in the future
and move m5.SimObject entirely to m5.objects.SimObject and only declare
it with SCons's SimObject(), but that won't quite work during this
transitional period, and it wouldn't give users a chance to move over to
the new name.

25bfa81ea8 scons: When importing SimObjects, use a copy of globals(). 
Use a copy of globals when importing SimObjects, instead of the real
deal that the SConscript runs under. This avoids polluting the
SConscript namespace.

1c233ee9d2 scons: Add sim_object and enums arguments to SimObject(). 
This will explicitly declare what SimObject and Enum types need to be set
up in C++, which will make importing all the SimObject modules during
the setup phase of SCons uneccessary.

1808da8f97 sim-se: Handle empty paths when resolving an "at" path. 
When the "path" argument is empty, use the file name of the node
referred to by the fd file descriptor. This matches the behavior of
"at" system calls when the TGT_AT_EMPTY_PATH flag is set. The system
calls themselves are responsible for checking for that flag, and
returning an error if an empty "path" is not allowed.

* https://gem5-review.googlesource.com/c/public/gem5/+/52184
* https://gem5-review.googlesource.com/c/public/gem5/+/52183

These changes, broadly speaking, remove the SimpeBoard as a superclass
and instead have all the boards inherit directly from the AbstractBoard.
It also fixes the order of operations (the order in which components are
incorporated and the board it setup).

82ef178d68 stdlib: Removing SingleChannelMemory 
This change removes the code base for SingleChannelMemory and
replaces it with MultiChannelMemory. muli_channel defines all
the classes that were defined by single_channel. Basically any
SingleChannelMemory could be thought of as a MultiChannelMemory
with 1 channel.

664fdd747a arch-arm, dev-arm: Add currEL function to the ISA class 
This utility is strictly ISA related. We are still keeping the
version accepting the TC as an argument; this is just
wrapping the ISA call.

In this way we are simplifying life for ISA devices, which have
a reference to the ISA object rather than a reference to the TC

883b8fe826 arch-arm,arch-sparc: Remove legacy stat for faults 
This is a legacy stat that was not easy to tie to a Stats::Group.

In ARM, this stat wasn't actually counting all faults, it was only
counting the faults that occured in 32-bit mode, so it's probably safe
to remove the stat (it was wrong anyway). For SPARC, it's also unlikely
anyone is depending on this stat for their research.

the MultiChannelMemory could be tested easier. Considering that

argparser to read the inputs.
