flash scripts: implement FCB/BCB upgrade
Newer U-Boot versions no longer write a BCB which includes the work around for errata e9609. However, we need to be able to upgrade modules which still have such BCB on-disk. Use the following process to upgrade modules: 1. Use the old U-Boot to flash a new U-Boot using the old format 2. Use the new U-Boot to replace the old BCB with the new BCB 3. Use the new U-Boot to flash the new U-Boot using the new format Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
