dumpimage - extract data from U-Boot images

       Please report bugs to the U-Boot bug tracker.

dumpimage  lists and extracts data from U-Boot images. If -l is specified, dumpimage lists the components
       in image.  Otherwise, dumpimage extracts the component at position to outfile.

       Create a multi-file image and then extract part of that image

-h     Print usage information and exit.

       -l     Print the header information for image, including a list of components.

       -ooutfile
              The file to write the dumped component to.

       -pposition
              Specify the position of the component to dump. This should be a numeric index, starting at  0.  If
              not specified, the default position is 0.

       -Ttype
              Specify  the type of the image. If not specified, the image type will be automatically detected. A
              list of supported image types may be printed by running mkimage-Tlist.

       -V     Print version information and exit.
