Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
