> ==================
> 
> So far creating a bootable SPL image for Allwinner based boards uses
> the mksunxiboot tool. Most other platforms seemed to have integrated this
> kind of functionality into the common mkimage tool.
> 
> Since there is nothing special about the Allwinner image in this respect,
> just add support for the so-called "eGON" image type into mkimage. If there
> was a particular reason this hasn't been done before, please let me know.
> 
> This will eventually allow us to remove mksunxiboot, but I leave it around
> for now in case of regressions and since some people depend on it from
> external projects.
> 
> Patch 1/3 splits some existing sunxi specific header file, so we can
> share the eGON header definition between the tools and the SPL.
> Patch 2/3 adds the actual support to mkimage, patch 3/3 then switches
> the Makefile to use mkimage instead of mksunxiboot.
> 
> I tested all 152 Allwinner boards by building each
> u-boot-sunxi-with-spl.bin and comparing them against the version created
> using mksunxiboot (using SOURCE_DATE_EPOCH and .scmversion to create
> reproducible builds, and by reverting just patch 3/3).
> All files before and after were identical.
> 
> Cheers,
> Andre
