Maybe mention the Net20DC in the help text too.

Thanks, r5848. I mentioned all Debug devices I know about briefly in
the help text. We should add more info about the non-NET20DC ones to the
wiki though.

So using a plugin pci card with that functionality is not possible?

Good point, no, that will not work, but it never did, because the
coreboot build would only have the code support for the onboard
southbridge.

If we want to support Debug Port on plugin cards then we need to
decouple the code from the southbridges, so that all or none Debug
Port support can be selected in Kconfig. Maybe it goes into drivers/
instead then..
