Yes, I really want to participate in the Lenovo G505S porting from AGESA to Native Init ! But, to be honest, I have never done such a task before, so my experience is probably not enough for doing this port alone by myself : I cannot even estimate the amount of necessary work and don't know where to start... (Dear Timothy, could you please point me to any good examples of AGESA --> Native Init porting?) However, I will be very glad to help as much as I could by being a build tester: I can constantly test these "native init" builds on my hardware - as many build iterations as it needed in order to help make "Native Init" a stable and good enough candidate for replacing AGESA
Also I will seriously consider donating some Money/Things to those coreboot developers who will make significant commits for bringing G505S "Native Init" port to life, although my financial abilities became very limited after Rubble currency collapse so unfortunately I cannot guarantee this type of support as well as how much would be the amount of donations...
Lenovo G505S uses quad core A10-5750M APU which is Richland architecture. This architecture does not include PSP hardware ( ARM TrustZone security co-processor) , so luckily this Family 15h RL laptop does not need a PSP blob ;-)
By the way there are just two AMD-based laptops that are supported by coreboot, and another one is HP M6-1035DX which has weaker hardware / smaller availability / lack of manufacturer support (HP quickly forgets their old laptop models and probably already stopped replacement motherboards production for this laptop - but I'd be happy to be wrong here) . As for now, G505S seems to be the only AMD laptop which is supported by coreboot and is really alive , so hopefully its code will be allowed to stay in its AGESA shape until a stable "Native Init" replacement will be introduced
Best regards, Vladimir Shipovalov

While the possibility of AMD AGESA boards 'removal' is being discussed, I would like to tell you about Lenovo G505S - which has Compal LA-A091P AMD Family 15h RL AGESA board.
- Did you know that Lenovo G505S is still widely available at some parts
of the world? (e.g. in Russia, 50+ online shops are still selling it)
- Did you know that Francis Rowe, head Libreboot developer, has proposed
the addition of G505S to Coreboot LTS Candidates list of laptops?
- Did you know that Compal will still be making LA-A091P laptop
motherboard, the primary component of G505S, at least until the end of 2018 year? (although these would be meant for Lenovo technical repair workshops, any person will be able to buy them by request even at 1pcs quantities)
It is unbelievable that some people here want to take alive-and-kicking motherboard and 'remove it': either 'remove' a support for it completely, or degrade it into a 'second class citizen' - by branching it off to some abandoned branch that nobody would care about. Don't know which is worse...
Slightly off topic, but if the Lenovo G505S uses a Family 15h processor it should be possible to port it over to native initialisation (thus ensuring it's continued existence as a first class citizen, even if this discussion comes up again eventually).
I was also unaware that true Family 15h CPUs had made their way into laptops; do you know if that particular device requires a PSP blob or not?
One last comment regarding removal. At minimum I would expect that none of the boards, chipsets, or CPUs shown in the board status repository from at least the past few months should be candidates for removal. As you can see K8 is definitely listed: http://review.coreboot.org/gitweb?p=board-status.git;a=summary
Thanks!
