Subject: [PATCH v4] ARM: dts: imx6qdl-nitrogen6x: Add SPI NOR partitions
Date: Tue, 28 Nov 2017 15:49:24 -0200	[thread overview]
Message-ID: <20171128174924.5149-1-otavio@ossystems.com.br> (raw)

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: bootloader
 mtd1: env
 mtd2: splash

Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>

Changes in v4:
 - drop lock flag

Changes in v3:
 - use lock instead of read-only (Gary Bisson)

Changes in v2:
 - rework labels (Fabio Estevam)
 - add read-only flags (Fabio Estevam)
