commit a15679d9390ef513a81aa9835483194accc1ae9f

    Simplify the flash slides
    
    - By removing the U-Boot NOR and SPI NOR details
    
    This section is already quite difficult to digest.
    I believe it's better to focus on NAND which is what we
    use the labs.
    
    Feel free to disagree :)
