# This device exists only because there are some devices that I don't
# want to have a Platform parameter because it would cause a cycle in
# the C++ that cannot be easily solved.
#
# The real solution to this problem is to pass the ParamXXX structure
# to the constructor, but with the express condition that SimObject
# parameter values are not to be available at construction time. If
# some further configuration must be done, it must be done during the
# initialization phase at which point all SimObject pointers will be
# valid.
