Hi, Clement
Just FYI. On MIPS barebox I use out-of-tree kexec-based ELF loader.
This efforts started in 2012 (sic!):
http://lists.infradead.org/pipermail/barebox/2012-December/011771.html
Alas! kexec patches are not mainlined still.
public kexec patches are available in my github repo, e.g.
https://github.com/frantony/barebox/commits/20170319.mips-malta-elf-linux
If your are interested in using kexec-style ELF loading I can prepare
patches on top of latest barebox master.
