3mdeb has been working on this. Here is some documentation with resources to get started: https://github.com/3mdeb/openpower-coreboot-docs. They've also given several recent talks about this, and many of their patches have been merged into upstream coreboot.

If you've got a Talos II or other POWER9 platform I'm sure they'd love some help testing it :-)
