I tested this on a Netgear R6250 V1 (BCM4708) and SMP worked.

You activated ARM_ERRATA_764369 for NSP is this not needed for NS?

You would have to read the ARM CPU register and then compare to ARM Errata to see whether the Errata affects NS or not.

Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores.
