- On some PSP versions, it's possible to run (fully free?) software on it[1]. However a lot of work would still be needed to write the RAM initialization code, etc.
There are also tools<ref>https://i.blackhat.com/USA-20/Wednesday/us-20-Buhren-All-You-Ever-Wanted-To-Know-About-The-AMD-Platform-Security-Processor-And-Were-Afraid-To-Emulate.pdf</href> to trace the boot of the PSP firmware. So it might be possible to use that to replay the RAM initialization and write or adapt a free software OS for it.
