Subject: [PATCH 09/11] ARM: rockchip: Add bootm handler for RKNS images
Date: Tue, 15 Jun 2021 16:16:39 +0200 [thread overview]
Message-ID: <20210615141641.31577-10-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210615141641.31577-1-s.hauer@pengutronix.de>
The rk3568 utilizes boot images starting with the magic 'RKNS'. Add a
bootm handler for these to allow them to be chainloaded.
