Devicetree files in RK3399 platform is synced from Linux, like other platforms does. Apart from these u-boot in rk3399 would also require some u-boot specific node like dmc. dmc node has big chunk of DDR timing parameters which are specific to specific board, and maintained with rk3399-sdram*.dtsi. So, create board specific -u-boot.dtsi files and move these sdram dtsi files accordingly. This would help of maintain u-boot specific changes separately without touching Linux dts(i) files which indeed easy for syncing from Linux between releases. These board specific -u-boot.dtsi can be extendible to add more u-boot specific nodes or properties in future.
