We also intend to submit patches for the SBC-S32V234[1] board in the
future and I believe that its 'compatible' should share this entry.
Would it therefore be preferable to update the description at this
moment and add a comment, like:

      - description: S32V234 based Boards
        items:
          - enum:
              - fsl,s32v234-evb           # S32V234-EVB2 Customer Evaluation Board
          - const: fsl,s32v234

or just replace the single-value 'enum' with a 'const' for now?

Regards,
Stefan
