10 .RB [\fIoptions\fP] " \-f [" "image tree source file" "]" " [" "uimage file name" "]"
23 system image, firmware images etc., either separate or combined.
29 .I legacy image
30 format concatenates the individual parts (for example, kernel image,
31 device tree blob and ramdisk image) and adds a 64 bytes header
33 image type, compression method, entry points, time stamp, checksums,
37 .I FIT (Flattened Image Tree) format
44 .B List image information:
48 mkimage lists the information contained in the header of an existing U-Boot image.
51 .B Create old legacy image:
63 .BI "\-T [" "image type" "]"
64 Set image type.
65 Pass \-h as the image to see the list of supported image type.
82 List the contents of an image.
85 .BI "\-n [" "image name" "]"
86 Set image name to 'image name'.
89 .BI "\-d [" "image data file" "]"
90 Use image data from 'image data file'.
97 .B Create FIT image:

116 After processing, move the image data outside the FIT and store a data offset
119 in each image will be replaced with 'data-offset' and 'data-size' properties.
124 .BI "\-f [" "image tree source file" " | " "auto" "]"
125 Image tree source file that describes the structure and contents of the
126 FIT image.
130 and -e are used to specify the image to include in the FIT and its attributes.
135 Indicates that an existing FIT image should be modified. No dtc

167 must be verified for the image to boot. Without this option, the verification
