Ok, did that.

This is actually a fix for booting linux-next with initramfs on barebox
and is the cause of some boot failures in our kernel-ci lab:
https://storage.kernelci.org/next/next-20161206/arm-imx_v6_v7_defconfig/lab-pengutronix/boot-imx6dl-riotboard.html

Maybe this should be merged to master instead of next?

Regards,
Jan

[PATCH] of: base: add chosen node if it does not exist when adding initrd

2016-12-08 Thread Philipp Zabel 
If the chosen node does not exist, of_add_initrd fails to pass the
initrd to the kernel. Instead it should create the chosen node, just
like of_fixup_bootargs does.
