Security Reference Manual for i.MX7Dual and 7Solo Applications Processors (Document Number: IMX7DSSRM Rev. 0, 03/2017) has described Manufacture-protection chip-authentication process module, and why/how this feature should be used. It seems a very good and useful feature. However the document doesn't seem to give a specific way to actually invoke the three main functions, MPPrivK-generation function, MPPubK-generation function and MPSign function. Do they automatically invoke at certain stage of execution, or need to issue some sort of command via bootrom or by setting some register?
Do we have any application note on this subject?
Thank you,
