Linux/AM5728: How to disable DSP core on the standard linux sdk

Part Number:AM5728

Tool/software: Linux

Hi champs,

I would like to disable all DSP core at standard Linux sdk.

Could you please indicate which file should I modify it ? 

I would like to disable all DSP and max frequency for both A15 , then I will create SDK for customer test.

I tried to see many manual to disable DSP. However, I couldn't find it ?
