>From my designer's info, these IPs' nor controller could use same
driver, and I had verified it. I think there's no need to update
mtk_nor_of_ids[], unless we find difference between these IPs(exactly
compared with mt8173).
How do you think?

And, we will add dts patches for new SOCs, are these patches should
applied with this documentation?
