And same boards do not report problems on the next?

If this is mt8183-kukui-jacuzzi-juniper-sku16.dts, then it looks like
bootloader adds /firmware node with missing address/size-cells. Is
bootloader updateable there? The dtc reports this as warning for almost
20 years, so I assume the bootloader is just junk or not using dtc.

+Cc Mediatek maintainers as it seems their board.
