That's different, as rx51_secure_dispatcher does the following:

- Use arguments + 1 instead of 4, we currently use just 4
- Disables local_irq and fiq, we are not doing that now
- Flushes and invalidates cache range, we are not doing that
- Calls omap_smc3 that only does mov r6, #0xff, and does not
  do mov r2, #4
- Missing nops after it's done

This just based on a quick look I did earlier. So just
because of the extra work it does we don't want to do it
even if it worked :)
