Hello,
on some systems (for example Fedora Core 4) U-Boot builds with the
following wanrings only:
...
In file included from /home/wd/git/u-boot/include/libfdt_env.h:33,
from fdt.c:51:

The suggested change works in image.h, for example like this:

#endif

#if defined(CONFIG_FIT)
#include <fdt.h>
#include <libfdt.h>
=======================================================================
However, for the FDT code this doesn't help, as we then will get
unresolved references for fdt32_to_cpu(), cpu_to_fdt32(),
fdt64_to_cpu() and cpu_to_fdt64().
The 32 bit accesses couldbe worked around by using htonl() resp.
ntohl(), but I don't know a good way for the 64 bit cases.
Is there a clean and portable way to do this?
Best regards,
Wolfgang Denk
