Subject: [PATCH 02/23] ARM: omap3: Add missing memory node in overo and torpedo boards
Date: Wed, 31 Aug 2016 12:35:16 +0200	[thread overview]
Message-ID: <1472639737-17586-3-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1472639737-17586-1-git-send-email-javier@osg.samsung.com>

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

But these boards don't have a memory node defined, so removing the
skeleton.dtsi inclusion from omap3.dtsi will cause a change in the
compiled DTB. Add a dummy memory node so the compiled DTB doesn't
change if the skeleton.dtsi is removed from omap3.dtsi.

Eventually the correct starting addresses and sizes should be used
but I didn't find that information.
