Subject: imx6: apalis: fix config survival after sysupgrade -n
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2f1a11d0089c9d4b675b0e1e8806e1e8e3be5a02;p=openwrt%2Fstaging%2Faparcar.git

imx6: apalis: fix config survival after sysupgrade -n

This patch fixes `sysupgrade -n` when flashed with rootfs of the same
size as currently running, so the rootfs_data wouldn't get destroyed and
thus survive reboot. So let's fix it by always cleaning up the content
of the rootfs_data during sysupgrade.
