I remember working on an issue related to "FSP asserts on IOM ready check" I guess on ICL RVP

It got fixed for me after making sure proper IOM binary was added using the fit tool.

I'm sure your setup is able to boot with vendor provided bios. Then other option is that you can extract iom.bin from a working bios & pack it into your generated coreboot fw. Then give it a try.

Hello again Michal,
I'd like to additionally ask you about a small detail regarding to the issue: What was the stepping that started to work?

I'm currently encountering this behavior on B-0. I really did have some really bad memory init errors on A-0 which was considered an engineering sample and swapping for B-0 solved it. Nevertheless, this MCE issue still persists on B-0 in my case.

Thanks for info.
