Hi,

I've done this yesterday, I've push a branch[1] that has the green
thread paches applied (except patches on usb mass storage gadget).
https://github.com/jmaselbas/barebox/tree/test_setjmp 

To test greenthread your can run the `poller -c` command in barebox's
prompt. To do you you'll need to enable CONFIG_POLLER_YIELD and define
CONFIG_HAS_ARCH_SJLJ

Best,
Jules
