Currently in arch and driver code that needs early access to the
flattened device tree it is necessary to add specific CFLAGS so that
when scripts/dtc/libfdt/libfdt.h is included the C preprocessor is able
to locate the libfdt versions of libfdt_env.h and fdt.h without
generating an error.

Until this is resolved with upstream DTC, what about adding dummy
libfdt.h, libfdt_env.h and fdt.h to include/linux? That would get this
out of the blocker path for merging this code.

2 of those already exist. Is it only a matter of adding fdt.h or is
there more to it?

This could also be carried as part of the import script to fix up.
