I compiled openpower firmware but it only produced skiboot, a kernel, and an initramfs (no hostboot, and no single firmware image that I can flash). there is no hostboot config for zz (the codename for the type of power9 server that I have) in the op-build repo. there is one for fsp systems (fsp = flexible service processor, which is a ppc476 core that serves a similar purpose to the bmc on openpower systems), but I am also missing an xml file which would be used for creating the firmware image.

now I’m stuck and don’t know what to do

(for context: I have a power9 server running the proprietary powervm firmware and I would like to replace it with openpower. I assumed this would be possible because openpower was initially developed on power7 (which never shipped openpower firmware), power8 L-series systems apparently supported both opal/openpower and phyp/powervm, and there was a config for zz in the op-build repo (and the documentation for it mentions systems using fsp) (also, there is an openbmc port for the fsp2), but I didn’t know that it was missing hostboot or those xml files. I still think it’s possible to get it running somehow, just very difficult and I’m not sure that I can do it.)
