This command can be used to extract fields and image payloads from Android Boot Image. It can be used for example to implement boot flow where dtb is taken from boot.img (as v2 incorporated dtb inside of boot.img). Using this command, one can obtain needed dtb file from boot.img in scripting manner, and then apply needed dtbo's (from "dtbo" partition) on top of that, providing then the resulting image to bootm command in order to boot the Android.
Also right now this command has the sub-command to get an address and size of recovery dtbo from recovery image. It can be further parsed using 'dtimg' command and merged into dtb file (for non-A/B devices only, see [1,2] for details).

Sorry I still think this name 'bootimg' is confusing. How would anyone know that it is specific to Android?
How about abootimg?
