How do you plan to add those additional hardware on the expansion bus ?

IIUC having them in DT and running on a system without the tile
connected will cause aborts, hence you are just adding bus definition.

Is there any use in having just the bus definition in DT. If you are
planning to add devices using overlays, can't the bus definition also
be added then ?

I am fine with the patch as such, just wanted to know the information.
