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. > Currently, when booting an elf file using "bootm /dev/mtdx", bootm will > simply pass the file to the bootm and the read done on it will read the > entire flash partition.
