Why?  mkimage is u-boot specific, and hence is maintained by u-boot.
If you're not using u-boot, then you don't need mkimage.  What is
wrong with it being a prereq like all the other tools we use?  If
you're doing embedded development, you're installing non-distribution
cross toolchain anyway.

dtc and mkimage are embedded development tools.  They belong with the
embedded development toolchain.  mkimage is already part of ELDK.
