Since there is a PLDM firmware update specification, a generic design
and implementation is a definite possibility.

Will you be able to update
a design section on firmware update? Some of the things I would like
to review via this doc update:
- How does this integrate with the current OpenBMC firmware update
architecture, and also with Redfish update service?
- What will PLDM run on? RBT or MCTP? MCTP over what binding?
- Do you anticipate changes to libmctp?
- How does this fit into the existing https://github.com/openbmc/pldm
design? What new components will you be adding? Will libpldm and pldmd
be impacted, and how?
- The 5.9 Linux Kernel has some APIs for PLDM based firmware update.
Can we use those?
- How do we plan to test this? Is hardware a must? Or are you planning
on mocking a PLDM responder?
I think a quick review of such a design doc will be beneficial before
delving into code. Also, please note - Richard and Sumanth (copied
them) are working on similar stuff as well. So there could be scope
for collaboration and to avoid likely duplicate effort. We do talk
about ongoing PLDM activities in OpenBMC in this meet -
