Flashing Optimization:



    After generating the list of tasks to execute, Fastboot will try and

    optimize the flashing of the dynamic partitions by constructing an

    optimized flash super task. Fastboot will explicitly pattern match the

    following commands and try and concatenate it into this task. (doing so

    will allow us to avoid the reboot into userspace fastbootd which takes

    significant time)



    //Optimizable Block

    reboot fastboot

    update-super                        ---> generate optimized flash super task

    $FOR EACH {dynamic partition}

        flash {dynamic partition}

The "getvar:%s" command is used to read client variables which
