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

From: Sasha Levin
Date: Fri Nov 22 2019 - 00:30:18 EST


From: Fabio Estevam <festevam@xxxxxxxxx>

[ 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.
