I've never heard of such things. PAPR/LoPAPR/LoPAR (pseries) is specified as an OpenFirmware platform, and I don't see that changing in the future given the way it's baked into the spec. And PowerNV is a minimal-runtime-services platform where the runtime abstraction (OPAL) calls don't include any sort of way to access disk devices.

Do you mean alternative firmware for PowerNV? I've heard people talking on and off about coreboot, but I don't see that becoming mainstream over the petitboot skiroot payload.

I don't see the pseries virtualization requirements changing away from OpenFirmware in the future either, given the OpenFirmware requirement has been a constant all the way back to CHRP.
