> Commit 47d73ba4f4a4 ("board: sifive: overwrite board_fdt_blob_setup in u-boot
> proper") added a board-specific implementation of board_fdt_blob_setup()
> which takes a pointer as the return value, but it does not return anything if
> CONFIG_OF_SEPARATE is not enabled. This will cause a build warning seen when
> testing booting S-mode U-Boot directly from QEMU, per the instructions in [1]:
