I am interested in coming up with a common (OpenBMC OEM level) set of 
Firmware NetFn commands that will allow all users of OpenBMC to be able 
to use common, open-source utilities to do firmware updates. If they are 
IPMI commands, this would include in-band (with KCS/BT for 
command/control and USB for transfer) or out-of-band (over RMCP+).

Rather than use the OEM NetFn, for firmware updates, we should be using 
the Firmware NetFn.  The entire Firmware NetFn is considered to be OEM 
per the IPMI spec. I would propose that we simply provide a common 
implementation for OpenBMC (as a provider library, of course, so it 
could be replaced if a downstream OEM doesn't want it).
