The patch doesn't apply to upstream - the Swift machine only exists in the
OpenBMC kernel tree. Please rebase the patch onto upstream and resend.

Is this how the board is strapped? I'm asking in case it's just copy/paste
from Palmetto, which was (unfortunately) strapped this way.

The patches for this are not upstream, and won't make it in their current
form. Please drop this node from the patch.

This driver is not upstream either, and we plan on dropping it from the
OpenBMC tree too. Please remove this node from the patch.
