From: Bin Meng Date: Sat, 11 Sep 2021 14:31:23 +0000 (+0800) Subject: board: sifive: Fix a potential build warning in board_fdt_blob_setup() X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a0cfe137157243d9cfcc928e0939b3d65274b554;p=u-boot.git board: sifive: Fix a potential build warning in board_fdt_blob_setup() 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]: 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.
