Hi guys,
I just went through most of the motherboards on coreboot webpage http://www.coreboot.org/Supported_Motherboards
I found only motherboard with Intel® ICH7 southbridge supports SMM. For these motherboards, they will set the CONFIG_HAVE_SMI_HANDLER=y the motherboards with Intel® 82801 series don't support SMM, because the CONFIG_HAVE_SMI_HANDLER was not setted after configuration and it will have compile errors if you set that flag manually.
In addition, most of motherboard with Intel ICH7 will have compile errors, there is only one mainboard will successfully compile and generate the coreboot.rom
It is Intel D945GCLF motherboard.
The source code I used is coreboot v4 lastest version. It would be great if someone could confirm this, thank you very much!
Best, Fengwei

I don't think that's a rule. SMM is used where it is needed.

This is obvious. The conclusion you can draw is that these boards do not need SMM.
In addition, most of motherboard with Intel ICH7 will have compile errors, there is only one mainboard will successfully compile and generate the coreboot.rom
This is not accurate. Note that there is an automated build system which build tests all boards on each commit, and at the moment all boards build without errors.

Why are you so interested in SMM?
As I mentioned above, coreboot will avoid using SMM unless it is a requirement for a particular platform.
If you want to add SMM to a platform where it is not used currently (and thus not required for coreboot) then it seems that you you have a lot of research and development ahead of you.

Ahh ICH4 also supports SMM :-)
