Subject: [PATCH] ARM: dts: imx6qdl-nitrogen6x: Add SPI NOR partitions
Date:   Fri, 24 Nov 2017 09:21:51 -0200
Message-Id: <20171124112151.2758-1-otavio@ossystems.com.br>
Organization: O.S. Systems Software LTDA.
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds the partitions definition for the SPI NOR to provide
backward compatibility with the documented[1] layout used with
Boundary Devices BSP.

1. https://boundarydevices.com/boot-flash-access-linux/

It exports to Linux:

 mtd0: U-Boot
 mtd1: U-Boot Environment
 mtd2: Bootsplash
