Subject: [PATCH] devicetree: zynqmp.dtsi: Add bootmode selection support
Date: Wed, 19 Feb 2020 13:20:36 +0100	[thread overview]
Message-ID: <20200219122036.24575-1-mike.looijmans@topic.nl> (raw)

Add bootmode override support for ZynqMP devices. Allows one to select
a boot device by running "reboot qspi32" for example. Activate config
item CONFIG_SYSCON_REBOOT_MODE to make this work.
