I'm not certain the CPU version, and without that it is difficult to know what errata's are present in the underlying hardware. My guess is that all present in NSP are present in NS (for UP and SMP). This would put it as: select ARM_ERRATA_754322 select ARM_ERRATA_775420 select ARM_ERRATA_764369 if SMP Would you like me to have them added?
