Public bug reported:
On RISC-V devices using a device-tree we rely on flash-kernel to
determine the relevant device-tree based on /proc/device-tree/model and
copy it to /boot. grub-update then adds a devicetree command to
/boot/grub/grub.cfg.
This allows booting with a current kernel even if the preinstalled
U-Boot (on SPI flash) is not able to provide a compatible device-tree.
Current subiquity 24.10.1 (latest/stable) does not invoke flash-kernel
and grub-update. Booting with an outdated U-Boot fails.
Subiquity 25.04+git1.482795dc in channel edge/latest/flash-kernel
resolves the issue but is not yet released to the latest/stable.
