Commit 47d73ba4f4 ("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]:
board/sifive/unleashed/unleashed.c: In function ‘board_fdt_blob_setup’:
board/sifive/unleashed/unleashed.c:125:1: warning: control reaches end of non-void function [-Wreturn-type]
Return &_end as the default case.
