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 - with the addition of two ROMs for ASUS AM1I-A and A88XM-E boards that I have.
AtomBIOS ROMs are required to enable the integrated and discrete VGA adapters, but to add the discrete GPU support for G505S you need to apply this change too: https://review.coreboot.org/c/coreboot/+/58745 = CB:57319 + CB:58652 + CB:58653 G505S dGPU support: scripts for applying the unofficial (not-merged-yet) patches
Save to ./coreboot/ then run ./extract_atombios_roms.sh and ./check... . Could analyze these ROMs with AtomDis - https://cgit.freedesktop.org/~mhopf/AtomDis/ Three ROMs are suitable for Lenovo G505S with A10-5750M APU installed, and two as a bonus: for ASUS AM1I-A with Athlon-5370 APU (iGPU HD-8400 / R3-Series) and for ASUS A88XM-E with A10-6700 APU installed (iGPU HD-8670D).
Here are the SHA256 checksums for these AtomBIOS ROMs:

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://firstname.lastname@example.org/thread/GZNWI...
