U-Boot always managed to use Linux devicetree files with respective bindings, but on the other hand u-boot also has it's own u-boot specific nodes or properties example u-boot,dm-pre-reloc which is required for SPL_OF_CONTROL to allocate particular node.
It is always a better job to add these u-boot specific nodes and properties into separate dts files which has an extension of -u-boot.dtsi This would help to sync the devicetrees from Linux whenever required instead of adding specific nodes.
So, create initial rk3399-u-boot.dtsi and move sdmmc, spi1 u-boot,dm-pre-reloc properties into it so-that the subsequent rk3399 boards can include the same on their board dtsi files.
This patch will create all preliminary infrastructure, like - create rk3399-u-boot.dtsi - create board specific -u-boot.dtsi files - include rk3399-u-boot.dtsi - move sdram dtsi into board -u-boot.dtsi files - move sdmmc, u-boot,dm-pre-reloc - move spi1, u-boot,dm-pre-reloc
This would help to - sync the dts(i) files from Linux whenever required instead of adding specific nodes. - easy to add u-boot specific changes like binman node into common -u-boot.dtsi file
