I'm afraid I don't have it anymore :(

SMC call itself is trivial, you can use smc_call @ u-boot:
arch/arm/cpu/armv8/fwcall.c
(this is code for armv8 in 64-bit mode, but you can easily port it to armv7)

As for adding custom commands - just use any existing as template (sleep may be a good idea :) ).

Regards,
Mateusz
