Browse code FVP: Do not power off secondary CPUs when booting an EL3 payload Normally, in the FVP port, secondary CPUs are immediately powered down if they are powered on at reset. However, when booting an EL3 payload, we need to keep them powered on as the requirement is for all CPUs to enter the EL3 payload image. This patch puts them in a holding pen instead of powering them off.

Normally, in the FVP port, secondary CPUs are immediately powered
down if they are powered on at reset. However, when booting an EL3
payload, we need to keep them powered on as the requirement is for
all CPUs to enter the EL3 payload image. This patch puts them in a
holding pen instead of powering them off.
