I am wondering whether TX1 or TX2 has TrustZone and proper drivers in the BSP.
(and TZ is adapted in default BSP)
That is, some special instructions, like DRM, may occur running-mode change into Secure.
Secure Boot of other threads is a little different approach, I think.
It may not use TrustZone in fact.
What I want to know is
- TX1/TX2 block diagram which shows where/how the TrustZone block is.
