asking for a full unconditional release of everything including releasing the signed keys for loading firmware( that doesn't make any sense, if you have a system that needs a signed key but the key is public what's the point ?). The whole announcement looks very rushed out to me( e.g. amd sales would go through the roof if they released the psp firmware, not going to happen). So my point is, from all these things the most likely to happen is amd releasing an ABI for it. It will give them the benefit of some press coverage and nothing more( like what broadcomm did with "open sourcing" drivers for the RPi 3 which was just the userland part while the opengl implementation was still part of a huge binary blob, but they did get the press coverage they wanted). So don't get your hopes too high on this.
