Dear Mike,
I am not sure what this is all about, but we already ported the G505s to coreboot. It would be good to get this chipset working with Timothy's non-AGESA ram init, which I was working on at an earlier time but got stuck and ran out of time. I believe the EC has been done too by Paul, so the only thing remaining apart from the hardest part (ram init) would be the vga init, (which Alex already did 95% for this particular hardware). I no longer have the laptop hardware with me so this is going to be problematic for me to do much work on it in the near future.
By the way, I'm not sure if you are allowed to redistribute proprietary roms/datasheets, but IANAL.
I wish you luck,
Damien

Good day! Together with my friend Ivan we have opened a new GitHub page,
https://github.com/g505s-opensource-researcher
and created 3 repositories there:
- g505s-atombios
AMD AtomBIOS video bios releases for G505S Integrated HD-8650G and discrete HD-8570M / R5-M230 GPUs
- g505s-proprietary
Proprietary stuff: InsydeH20 closed source BIOS files, documents, binaries and datasheets for G505S
Their files were described at our previous messages:
https://mail.coreboot.org/pipermail/coreboot/2017-July/084660.html https://mail.coreboot.org/pipermail/coreboot/2017-July/084671.html https://mail.coreboot.org/pipermail/coreboot/2017-June/084569.html
All the SHA-256 checksums are available at sha256sum.txt text files
Also, we are going to set up 3) a bit later:
- g505s-coreboot
coreboot open source BIOS releases for AMD-based Lenovo G505S laptop with A10-5750M quad core APU
"3)" could be especially useful for the people who just recently became interested at coreboot/SeaBIOS projects - and would like to quickly test on their G505S laptop because of the official BIOS shortcomings (WiFi whitelist / poor thermal management)
By the way, there were two typos at Ivan's cbfstool.sh script - two missing "" characters at the end of line. g505s-atombios repository has a working version
Have the great weekends and happy hacking ;-)
Wish you all the best, Mike Banon
