CorebootPayloadPkg doesn't have the hooks requires for CSM, you'd need to use OMVH as a model to integrate the CSM. I've played around with it but never got it working. Maybe it would be better to try and integrate with UefiPayloadPkg?

Right, but I'm not building for OVMF, I'm making a Coreboot payload.
Does that option still exist there?

Hi all- I've found only vague references to doing this (

and no real guides / examples.
Before I go on a wild goose chase, has anyone tried this before?
Basically compile with CONFIG_CSM=y, then copy the binary into the EDK2 tree and build ovmf with -D CSM_ENABLE.
