Document ARM TrustZone (similar to Intel ME) vs Librem5 Security
®i.MX 8M Quad core Cortex A53, 64bit ARM @max 1.5GHz (auxiliary Cortex M4)
ARM processors have TrustZone.
TrustZone is similar to Intel ME. A whole operating system running in parallel to the real operating system.
I guess you've extensively researched that CPU. Could you please kindly share your thoughts on Arm TrustZone?
Did you disable or neuter ARM TrustZone in Librem5?
Does Librem5 use ARM TrustZone?
Are contents of ARM TrustZone modifiable by user?
