Subject: [PATCH] arm: dts: am335x-boneblack-common: fix memory size
Date:   Mon,  6 Jan 2020 16:09:08 +0300
Message-Id: <20200106130909.7697-1-matwey@sai.msu.ru>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

BeagleBone Black series is equipped with 512MB RAM
whereas only 256MB is included from am335x-bone-common.dtsi

This leads to an issue with unusual setups when devicetree
is loaded by GRUB2 directly.
