Looks like AMD is locking down their hardware and locking out the users and costomers of the hardware.

Through a strategic technology partnership with ARM, AMD will integrate the established ARM(R) TrustZone(R) technology into future Accelerated Processing Units (APUs) via a system-on-a-chip (SoC) design methodology.
In a presentation this week at the AMD Fusion Developer Summit 2012 (AFDS), AMD Senior Vice President and Chief Information Officer Mike Wolfe described AMD's vision to advance computing security by enhancing AMD's existing security technologies. This is expected to include developing a platform security processor using an ARM Cortex(TM)-A5 CPU that features TrustZone technology, to monitor and help protect against malicious access to sensitive data and operations at the hardware level.
This isn't real security. It's a way of preventing users from access to the hardware they they paid for and preventing users from using software of they choose to use.
