mvebu: uDPU: add sysupgrade support
This patch adds sysupgrade, uboot-env and networking support for Methode uDPU device. Device features 4 partitions: ----------------------------------------- | boot | recovery | rootfs | misc | | (ext4) | (ext4) | (fsf2) | (f2fs) | _________________________________________ Idea was to use f2fs only but the u-boot currently lacks support so first 2 partition are ext4 to be u-boot readable, and this was a reason why custom build and sysupgrade sections were required. On the sysupgrade, boot and rootfs partitions are updated, firmare image and user configuration is saved on the misc partition and if the upgrade was successfull, recovery partition will be updated on after the reboot from preinit script. If the sysupgrade fails for any reason, device will fallback to recovery initramfs image. Signed-off-by: Vladimir Vid <vladimir.vid@sartura.hr>
