Subject: [DistroKit] [PATCH 07/14] v7a: add RAUC support for rpi3
Date: Fri, 23 Jun 2023 14:47:48 +0200	[thread overview]
Message-ID: <20230623124755.2292833-8-rhi@pengutronix.de> (raw)
In-Reply-To: <20230623124755.2292833-1-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
