It seems like some of the folks that used to be at OzLabs did it as a PoC https://www.flamingspork.com/blog/2015/10/20/tianocore-uefi-ported-to-openpower/. One of the exciting things about OpenPower was that everything above the gates was open in a way only RISC-V seems a chance of repeating any time soon. There are no practical limits to the firmware and runtime service; if you haven't seen this you both might enjoy it https://www.flamingspork.com/blog/2016/10/30/windows-nt4-for-powerpc-guest-on-opal-on-power8-in-qemu/. Practically speaking, with Petitboot (which FreeBSD on PowerNV uses) there isn't much point to go to something like UEFI. It's literally Unix vs DOS-like. The primary targets are Raptor POWER9 hardware and LoPAPR/LoPAR VMs (kvm, PowerVM) and I don't see any near term indication of the ISA expanding to new platforms that would concern FreeBSD.
