well, that suits my goals as well, and I'm working on the same thing :-)

I have linux and root file system in flash on a KGPE-d16. All my tools in
root file system are written in Go, i.e. not busybox.  I'm currently trying
to get kexec in Go done. It's a pain but evidently in 4.x kexec got far
easier to work with.

I'm hitting one problem: I need to get a working 4.7.0 kernel as a payload.
I have a 3.18 working fine, as payload, but the 4.7.0 never puts out any
serial output. If you have a 4.x.+ kernel config that works as a payload,
let me know.

I'm happy to see you blazing the trail :-)
