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 fixes a small annoyance in mkimage -T list. Patch 2/3 adds the actually support to mkimage, patch 3/3 then switches the Makefile to use mkimage instead of mksunxiboot.
I tested all 144 Allwinner boards by building each sunxi-spl.bin and comparing it against the version created using mksunxiboot (using SOURCE_DATE_EPOCH and .scmversion to create reproducible builds). All files before and after were identical.
Cheers, Andre
