If U-Boot CONFIG_OF_SEPARATE is defined [1], then the device tree will be built and placed in a u-boot.dtb file alongside u-boot.bin. When BR2_TARGET_UBOOT_FORMAT_DTB is enabled, buildroot will copy u-boot.dtb to $(BINARIES_DIR). This is useful for RISC-V platforms that want to build OpenSBI with an external DTB by using FW_FDT_PATH [2].

OpenSBI aims to provide an open-source and extensible

implementation of the RISC-V SBI specification for a platform
|
|
specific firmware (M-mode) and a general purpose OS,
|
|
hypervisor or bootloader (S-mode or HS-mode). OpenSBI
|
|
implementation can be easily extended by RISC-V platform or

System-on-Chip vendors to fit a particular hadware

configuration.
