Subject: [DistroKit] [PATCH v3 07/14] v7a: add RAUC support for rpi3
Date: Thu, 27 Apr 2023 12:01:27 +0200 [thread overview]
Message-ID: <20230427100134.2934937-8-rhi@pengutronix.de> (raw)
In-Reply-To: <20230427100134.2934937-1-rhi@pengutronix.de>
* Enable barebox bootchooser framework
* Add a redundant root partition to the genimage config. The state and
environment partitions can live in the first 4 MiB of the SD card, so
move the the boot partition by the same amount.
* Add appropriate variables to the barebox defaultenv so the bootchooser
can decide into which partition to boot
* Add a state backend to the device tree fragment
* Map partitions in rauc-udev compatibility layer
