Why not define this as "arch/arm/dts/k3-j784s4-evm.dtb"? Seems we use this as a hacky way to change this item based on CONFIG_DEFAULT_DEVICE_TREE as that DT will be renamed "u-boot.dtb". But I'm not sure what that gains us. And why only do it for U-Boot and not SPL_? If runtime selection is not working then we still have the wrong DTB for SPL just the same.
It also means we have in some builds we have a node named "j784s4_evm_dtb" that contains the SK DTB, and the node called "am69_sk_dtb" *also* contains the SK DTB..
