This patch series contains a few changes to the video core fixups where the desired behaviour is obvious from raspberry device trees. These were tested on a Raspberry Pi 4B. There's a few more differences between the video core device tree and the one provided by barebox for which a discussion is welcome: - After a [recent change][link1] the `/chosen` node of the device tree is now fully copied from the video core device tree. This could possibly be restricted to only copy relevant properties. - The properties `memreserve` and `serial-number` of the root node are added by the video core and could also be copied. - The property `model` of the root node is updated with the specific hardware revision of the pi. - The video core adds the two aliases `i2c_arm` and `i2c_vc` (as properties to the `/aliases` node). As the [raspberrypi documentation][link2] suggests to use the former for writing overlays, it should maybe also be copied as a fixup.
