I've confirmed that the ethernet ports work seamlessly on AMI stock firmware

Thanks, so we will need further analysis from @miczyg1

The drivers do not install automatically for i225/i226 controllers both on AMI and Dasharo. Installing a random i225/i226 driver may cause some problems...

Other devices that are driverless are SM Bus controller, GPIO controller, SPI controller, I2C controllers. Not sure why but there are a lots of drivers which matches the compatible device IDs in the Windows Update Catalog, but none of them want to apply automatically.

Will try with this one https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html (29.0.1) and see if I can reproduce.

It appears we have hit a bug with PCH PCIe power/clock gating from this comment:

https://github.com/coreboot/coreboot/blob/master/src/soc/intel/alderlake/fsp_params.c#L933

So I had to enable CLKSRCREQs, assign the clocks and change FSP type to IoT (for the UPD to be present). In order to remain some power savings I also enabled ASPM. Now I could install the drivers for all I226 Ethernet Controllers in Windows without a BSOD.
