Nothing improved here.

Why, for a given board, would you always boot device in one specific
mode but not the other? This does not look like property of DT.

And more of ignored feedback. I stop now.

This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.

Best regards,
