OMAP also uses smc: arch/arm/mach-omap2/omap44xx-smc.S

There's no interface defined for smc because it's highly vendor and
implementation specific.  It's just like a SWI (or svc) where it
causes entry via a vector into a priviledged mode, which can be
thought of being similar to a branch to a vector with a mode switch.
