Expose xyz.openbmc_project.Inventory.Decorator.Asset for system table

[jsalzano92]

I can understand that in some cases the system table data is redundant, but why are we not exposing the xyz.openbmc_project.Inventory.Decorator.Asset interface for the system information?

I would suggest it be a compile time flag, disabled by default to not conflict with the entity-manager.

Maybe I am missing something, was this not part of smbios-mdr for a reason?
