There's an unresolved reference to LMB functions. This code compiles
without a patch (i.e. it is not disabled by the preprocessor or externally),
but when linking, since this function is not called, it is discarded
(you can check on a clean build with the command
aarch64-linux-gnu-objdump -d u-boot | grep image_setup_libfdt).
I think it's worth fixing this bug too.
