ARM Trusted Firmware, number of cpu cores..

Hi all,

I have two questions about ARM Trusted Firmware. I suppose that I already have answer for one of them..

  1. Does Trusted Operating System (at Secure EL1) use or can use, more than one cpu core, or it always executes on one core?
  2. Does bl31, runtime firmware, use all cpus cores, or just one? (primary)

"During warm boot, BL3-1 is executed by all CPUs"

From - porting-guide.md doc

Thanks,
