I just tried building mainline now.  It is at commit f5a246eab9.

The build still fails for me at this commit.

I can't reproduce this.

Same here. It builds fine for me.

Thanks all for confirming it works.

I just figured it out on my end.  Here is how it gets broken for me.

- Before commit cd29672 (dtc: import latest upstream dtc) gets in,
  I did a build without O=<output_dir>.  It results in a copy of those
  libfdt files in arch/arm/boot/compressed.

- After the commit gets in, I start a build with O=imx parameter.  When
  compiling imx/arch/arm/boot/compressed/fdt_ro.c, the #include <libfdt.h>
  in fdt_ro.c seems to match the one left in arch/arm/boot/compressed/
  from last build rather than imx/arch/arm/boot/compressed/libfdt.h.

Cleaning the libfdt copies in arch/arm/boot/compressed fixes the
problem.  Not sure why it's not "libfdt.h" but <libfdt.h> is used as
the inclusion though, since the .h and .c are in the same folder.
