Does the presence of SCM hardware imply SMP?  From reading this, it's unclear
why the dependence on SMP - it looks like scm.c is something that hardware that
has one ARM processor and a 'secure processor' would still want.  Or is the
'secure processor' just another (arbitrarily labeled) ARM CPU participating
as a full SMP processor?
