How to control the SPNIDEN signal in iMX53 qsb?

The ARM architecture manual refers different debug authentication signals like DBGEN, SPNIDEN, SPIDEN, and NIDEN. However, from the iMX53 reference manual, I can only find description of how to control the DBGEN signal. Is there anyway we can control the other signals from the board?


Thanks for any help and discussion!
