STM32MP157F-EV1 - How to force all processes to run on Core 0?

I'm attempting to run a critical process on Core 1 (A7 processor) while keeping all other processes on Core 0. I've had success with 'taskset' to get my critical process assigned to Core 1. I'm struggling with how to default all other processes to run on Core 0. 

Can someone show me how to do this on the supplied OpenSTLinux platform for this processor? The internet mentions isolcpus a lot but I'm not finding support for that command on this processor. How can it be done?
