The other cores on my Soc need SGI to be waken up from reset state.
Could any one header and functions I need to include and used for?

It even comes with comments:
/*
* Send the secondary CPU a soft interrupt, thereby causing
* the boot monitor to read the system wide flags register,
* and branch to the address found there.
*/
gic_raise_softirq(cpumask_of(cpu), 0);
