Well, I don't think it is dead code cause the hang() is called in some ways.
This patch opens just the possibility to specialize the hang() by for
example a specific board. Maybe this could also be used for specific
hang() for different arches when we get closer to the common board files.
It is correct that we do not need this patch now and I can handle it
here in my own tree.
