Subject: [PATCH AUTOSEL 4.19 015/219] ARM: dts: imx6sl: Fix memory node duplication

From: Sasha Levin <[email-masked]>
Date: Fri, 22 Nov 2019 00:26:37 -0500

From: Fabio Estevam <[email-masked]>

[ Upstream commit 7fa8ab65ee15e386558ac5e971004712da91e2dd ]

Boards based on imx6sl have duplicate memory nodes:

- One coming from the board dts file: memory@

- One coming from the imx6sl.dtsi file.

Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.
