Subject[PATCH 4.9 165/329] powerpc/boot: Fix random libfdt related build errors
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <linux@roeck-us.net>

[ Upstream commit 64c3f648c25d108f346fdc96c15180c6b7d250e9 ]

Once in a while I see build errors similar to the following
when building images from a clean tree.

Building powerpc:virtex-ml507:44x/virtex5_defconfig ... failed
------------
Error log:
arch/powerpc/boot/treeboot-akebono.c:37:20: fatal error:
libfdt.h: No such file or directory

Building powerpc:bamboo:smpdev:44x/bamboo_defconfig ... failed
------------
Error log:
arch/powerpc/boot/treeboot-akebono.c:37:20: fatal error:
libfdt.h: No such file or directory

arch/powerpc/boot/treeboot-currituck.c:35:20: fatal error:
libfdt.h: No such file or directory

Rebuilds will succeed.

Turns out that several source files in arch/powerpc/boot/ include
libfdt.h, but Makefile dependencies are incomplete. Let's fix that.
