So, this belongs to the same group as common/fdt_support.c, which is a collection of U-Boot own fdt helpers. Move lib/libfdt/fdt_region.c to common/fdt_region.c . This is necessary only when CONFIG_(SPL_TPL_)_FIT_SIGNATURE is enabled. Signed-off-by: Masahiro Yamada Signed-off-by: Masahiro Yamada --- I am resending this after two years since v1. My previous attempt sank by this comment: http://patchwork.ozlabs.org/project/uboot/patch/1521623017-29312-5-git-send-email-yamada.masahiro at socionext.com/#1881196 Two years have passed, but I still do not see this file in upstream DTC.
