fdt: Add board specific dts inclusion
Some architectures, for example Microblaze, doesn't need a splitted device tree because every Microblaze hw design is different. The individuell Microblaze device tree will be auto generated by FPGA design tools and could be used directly with dtc. The auto generated dts for Microblaze can not processed by CPP. Unfortunately that is the default procedure in U-Boot to merge a splitted device tree (substitution of ARCH_CPU_DTS). Microblaze will never use the ARCH_CPU_DTS substitution and we introduce the new board specific substitution variable BOARD_DTS that points into vendor/board/dts subdir with the file name of CONFIG_DEFAULT_DEVICE_TREE. The common dts file in vendor/dts subdir (defined by CONFIG_DEFAULT_DEVICE_TREE) contain a single include line that can processed by CPP: /include/ BOARD_DTS Signed-off-by: Stephan Linz <> Tested-by: Michal Simek <> Acked-by: Simon Glass <>
