Denverton documentation?

ohmantics — Thu, 29 Jan 2026 23:02:08 GMT

I'm trying to do some support work on an Atom C3xxx board for coreboot.

The documentation is a bit thin. For example, there's some kind of BMC support at i2c address 0x44 on the i801 bus. The closest matching documentation I've found is an abandoned Linux patch set from Intel for the Lewisburg chips that is quite similar, but not the same, and I was able to find a description of this BMC support in the 600 PCH documentation. The Denverton docs I've examined don't mention it at all.

Am I missing where it's documented? If it's covered under NDA, then why since the same feature is public in Lewisburg?

Hello @ohmantics,

Thank you for contacting Intel Embedded Community.

There is more information under CNDA but you will need a Premier account to get access to it.
