4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Javier Martinez Canillas <javier@osg.samsung.com>

commit 3d37d41a148c32389ed360e10a9f8a7cd37ce166 upstream.

Commit d1f3156fc8c7 ("ARM: dts: omap2: Remove skeleton.dtsi usage")
removed the skeleton.dtsi usage since we want to get rid of it.

But this can cause issues when booting a kernel with a boot-loader
that doesn't create a chosen node if this isn't present in the DTB
since the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info.
