Stefan Agner fa9d977f97 mediatek: filogic: wax220: support factory image ... Enable building a factory image which can be flashed through the OEM firmware's web interface. It seems that the web interface requires a minimum file size of 10MiB, otherwise it will not accept the image. The update image is a regular sysupgrade tarball packed in a Netgear encrypted image. The Netgear encrypted image is the same as used in WAX202 or WAX206, including the encryption keys and IV. This adds a script which creates the rootfs_data volume on first startup. This is required since the OEM firmware's sysupgrade scripts do not create such a paritition. Note that any script ordered after 70_initramfs_test will not get executed on initramfs. Hence this new script 75_rootfs_prepare won't create the rootfs_data volume when using the recovery initramfs. Also, this deletes the kernel_backup and rootfs_backup volumes in case we have to create the rootfs_data volumes. This makes sure that OpenWrt is the actual backup firmware instead of the stock firmware.
