    ifdfake - Create an IFD with just a section layout
    This new tool called `ifdfake` just creates an empty Intel Firmware
    Descriptor (IFD) and writes the IFD signature plus the section layout
    given on the command line.
        usage: ifdfake [(-b|-m|-g|-p) <start>:<end>]... <output file>
           -b | --bios       <start>:<end>   BIOS region
           -m | --me         <start>:<end>   Intel ME region
           -g | --gbe        <start>:<end>   Gigabit Ethernet region
           -p | --platform   <start>:<end>   Platform Data region
           -h | --help                       print this help
        <start> and <end> bounds are given in Bytes, the <end> bound is inclusive.
        All regions must be multiples of 4K in size and 4K aligned.
        The descriptor region always resides in the first 4K.
        An IFD created with ifdfake won't work as a replacement for a real IFD.
        Never try to flash such an IFD to your board!
    The output of ifdfake can be utilized to build an image with just the
    later added sections (like coreboot itself) being valid. The resulting
    image can then be partially written to a machines flash ROM to just
    update coreboot (i.e. the BIOS section).
