Secure Memory Definition on LS1046A

Hello,

I'm seeking clarification regarding the concept of Secure Memory and Non-Secure Memory on LS1046A. Although I've gone through the relevant manuals/documents, I'm still unclear about their exact implementation.

Could someone provide an explanation or definition of Secure Memory based on NXP's perspective?

Thank you,
Faizan

They are related to the TZ ARM.

The TrustZone Address Space Controller (TZASC) is used to facilitates partitioning system main memory into TZ secure and TZ non-secure memory regions.

They will be used to load Trust firmware and/or something related to encryption as well.
