No, it is not licensed from Arm. AMD's PSP is a system built by AMD itself, it just happened for them to buy Arm cores to build their system.

They could have used MIPS, PowerPC or any other CPU cores for PSP, they just decided to go with Arm.

IIRC it also heavily depends on ARM's TrustZone architecture, it's not like they just "happened" to use ARM.

I mean, they did license it from ARM; it's a Cortex A5 last time I checked.
