Personally I'd like to see anything that's not a fixed HW property be
omitted in the DTS and injected by the boot firmware. Certainly anything
which is a property of the FW should be injected by that FW.
That would cover:
- Any enable-method property and related properties and/or nodes. This
is heavily dependent on the boot firmware configuration, and can
differ substantially between instances of a given board.
- Most /memreserve/ uses (as these typically protect firmware or
- Any memory nodes where memory can be dynamically populated on the
- CPU nodes if the presence of said CPUs is dynamically determined.
In the long term I'd like to see DTS get fully decoupled from the
