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 :)
Regards,
Tony
