Is this intended only for downstream u-boot only, or also for upstream
libfdt?

If it's u-boot only, you don't really need the #ifdef UBOOT.  If it's
for upstream, then it shouldn't have u-boot specific stuff.

In general the environment into which you're embedding libfdt (u-boot
in this case) should provide libfdt_env.h.  The one included in
upstream libfdt is essentially just an example version designed to
work with POSIX userspace.
