Hello

First of all thank you for your great work, I mean coreboot, it's really 
cool

I have mainboad Supermicro X11SSM-F rev 1.01, which almost the same as 
supported X11SSH-TF. Any chance that it will work fine with ROM for 
X11SSH-TF?

Best regards

I do not see any reason it shouldn't. BMC, chipset and supported
processors are the same. There are small differences in PCI Express
topology which should be adjusted in devicetree and/or FSP config, but
it should still boot. IIRC flash descriptor handles the PCI Express lane
configuration, so small changes in devicetree and/or  FSP config eventually.

Somebody is working on it: https://review.coreboot.org/c/coreboot/+/35427
I would recommend messaging him about the port status. He is also active on
IRC, if you prefer less formal and more spontaneous communication channels.

Please do NOT suggest running coreboot ROMs for mainboard X on something
that is not mainboard X. If GPIO settings for the southbridge and/or SuperIO
differ between boards X and Y, running coreboot for board X on board Y can
result in short-circuits, and cause permanent hardware damage. And replacing
the SuperIO, southbridge, or even the whole SoC on some board, is a very
laborious task which requires expensive, specialized equipment and skills,
so it is impractical to do for most people.

Yep, you are right. I was a little bit too hasty.  I have just recently
tested a coreboot on mainboards like these with just different product
suffix and it occurred to have the same GPIO configuration. It is quite
unlikely that the GPIOs will change. Like you said, replacing the
components is expensive so I doubt board vendors do that for similar
mainboards. However still significant enough to not ignore it.

Thank you for correction Angel.
