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?
Thanks,
