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.
I couldn't get the IOM working despite preserving the ME region during
flash updates. So literalyl I have been using the same IOM binary as
shipped. Using the same IOM binary doesn't guarantee the correct
operation of the TCSS and ends up in assert. Why? Because for some
reason an engineering sample PCH have been forcing the ME into disabled
state. No command could get ME out of this state which is probably the
reason why IOM was not working correctly as well (ME didn't load the
firmware?) or the FSP was not compatible with pre-production silicon.

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.
