Hello Mike Banon,
I'd like you to do a code review. Please visit

to review the following change.

G505S AtomBIOS ROMs: known good binaries with a script to check their SHA256
This change is a mirror for the known good AMD Lenovo G505S AtomBIOS ROMs from this repository - https://github.com/g505s-opensource-researcher/g505s-atombios
AtomBIOS ROMs are required to enable the integrated and discrete VGA adapters, however to add the discrete GPU support you will also need to apply these patches: https://review.coreboot.org/c/coreboot/+/31929 G505S dGPU support: scripts for applying the unofficial (not-merged-yet) patches
Here are the SHA256 checksums for these AtomBIOS ROMs:
6104e6989ea3f494d7bfa30573bf38e830f1068bab9980caec5e890e0ccbfced ./pci1002,990b.rom - for integrated GPU (iGPU) HD-8650G 6052b5def3fda2a93f6c4d55ec91b819429e212e26cdb8e0fcca54599c9c92ed ./pci1002,6663.rom - for discrete GPU (dGPU) HD-8570M 15d74515332bc512de66e0dc910d8600aeb134bf715bbc34a4faac0257f4a0dc ./pci1002,6665.rom - for discrete GPU (dGPU) R5-M230
Save to ./coreboot/ then run ./extract_atombios_roms.sh and ./check... . Could analyze these ROMs with AtomDis - https://cgit.freedesktop.org/~mhopf/AtomDis/
pci1002,990b.rom (for iGPU HD-8650G) has been taken from G505S with R5-M230, and despite the tiny voltage difference - it's working great for all G505S versions. https://mail.coreboot.org/hyperkitty/list/coreboot@coreboot.org/thread/ GZNWISLFHUTYN6C7RTWSQUMJIFOUHMED/
