+Subject: rockchip: fix broken squashfs sysupgrade
+
+The rockchip platform supports squashfs SD card images. However, the
+resulting image is not padded to completely fill the rootfs partition.
+
+Because of that, the f2fs overlay might not be erased, resulting in
+uci-defaults not bing executed or the configuration not being erased,
+even though drop config was selected.
+
+Modify the image generation process so the image is padded to cover the
+entire root filesystem partition.
