ARM TrustZone technical details for cortex-a7

Yusuf Sabitov

Hi everybody.

I was working/researching on ARM TrustZone. I have to implement it for the SoC(t113) based on cortex-a7. I was struggling to find information on how TrustZone works specifically on Cortex-A7 on the internet.

I found great documentations on trustzone : https://developer.arm.com/documentation/ddi0333/h/programmer-s-model/secure-world-and-non-secure-world-operation-with-trustzone/how-the-secure-model-works?lang=en ,

https://developer.arm.com/documentation/ddi0333/h/programmer-s-model/operating-modes?lang=en

developer.arm.com/.../registers

However, this is for ARM1176JZ-S. My question is, are these documents relevant for Cortex-A7. If no where can I find detailed explanation on trustzone for Cortex-A7 ?
