Once we've had a discussion here on the list, I can move this to Gerrit with some more details. I'd say reading the MCTP proposal from Jeremy should be a precursor to reading this.

Also I'd like to draw your attention to our need of keeping OpenBMC compatible with OpenPOWER Firmware for P8 family. If you're planning to switch to PLDM/MCTP for BMC-to-PNOR communications, we'd need support for that in PNOR for P8.
P8 is going to remain our main CPU until P9+ is released, but we are very interested in resolving the sensor count limit problems. We're currently developing a workaround for IPMI in context of https://github.com/openbmc/openbmc/issues/3417
