Sorry for the delay in responding.

libfdt_env.h is imported from an upstream project, using
the script scripts/dtc/update-dtc-source.sh.  Inside
that script are some 'sed' commands to modify the
imported files before committing them.  Please add
a sed command to make the change that the proposed
patch makes.

Thanks,

Frank
