The linked list of AMD processors is mobile 3D APUs under codename “Kaveri”. It is well documented that the successor to Steamroller marked the introduction of the PSP. But there is no concrete statement about which chips were the first to have the PSP. Wikipedia states the linked group of APUs have:

• Integrated custom ARM Cortex-A5 co-processor[47] with TrustZone Security Extensions[48]

The footnote does not support the claim. Can anyone confirm or deny whether Kaveri mobile chips have a PSP?

I’m guessing this is relevant to OSHW because PSP is dodgy closed-source anti-consumer garbage and it’s aligned with OSHW to avoid it. If there are still transparancy issues even with pre-spychip AMD APUs, I’ll apologize in advance for being off-topic.
