These are monitor mode secure API's and they can be executed
on any CPU.

I am talking about the services like secure encryption/decryption,
secure copy, saving secure RAM etc.

These services can't be executed on CPU1 and hence the concern.
There is entire secure middle-ware which runs in parallel with Linux
and all it's services are bound to CPU0 only.
