OpenSTLinux 6.1 (Scarthgap) Optee delay during boot.

Hi,

I am in the process of migrating my application to OpenSTLinux 6.1 (Scarthgap) and we are targeting a boot time of ≤10 seconds. while working on this, I observed that the OP-TEE layer takes some extra time during  secondary CPU initialization. As OP-TEE is new, I would like have some help in understanding the root cause of this delay and whether any optimization is possible in this phase.

I am using STM32MP157A Hardware. Below reference image is attached.
