When firmware is staged check if the platform / kernel also supports live firmware activation and include that state at both the dimm and bus level. The "last activate result" is included only as a hint to whether a powercycle is required to activate the current image. If firmware activation fails the "need_powercycle" flag will appear, if firmware activation is successful then the "current_version" field will be up-to-date.
