mvebu: Add turris-omnia.bootscript
In contrast to the U-Boot version shipped with older versions of Turris Omnia (CZ11NIC13, CZ11NIC20), the version shipped with Turris Omnia 2019 (CZ11NIC23) relies on the existence of /boot.scr. Consequently, add a suitable boot script to the sysupgrade image. Flash instructions for Turris Omnia 2019: - Download openwrt-...-sysupgrade.img.gz, gunzip it, and copy the resulting .img file to the root of a USB flash drive (FAT32 or ext2/3/4). - Enter a rescue shell: Either via 5-LED reset and ssh root@192.168.1.1 on LAN port 4, or via 7-LED reset and the serial console. - Insert the USB drive and mount it: mkdir /mnt; mount /dev/sda1 /mnt - Flash the OpenWrt image to eMMC: dd if=/mnt/openwrt-...-sysupgrade.img of=/dev/mmcblk0 bs=4096 conv=fsync - Reboot. Flash instructions using a temporary "medkit" installation were written for the older versions of Turris Omnia, and will *not* work on the Turris Omnia 2019.
