I think that at least X86_AMD_PLATFORM_DEVICE and MFD_INTEL_LPSS_PCI could be common enough to match within the category of needed to run in normal (or common) user mode(s). I can send a patch with only these two options. But, yes, the main purpose after this patch is the serial console for CI. I saw that there are already some configs with a specific purpose (tiny.config and xen.config). So, I am wondering if would be acceptable support another specific config for CI (i.e kernelci.config). Will it be acceptable? Thanks, Enric
