The LeMaker HiKey board has been failing to boot the Factory kernel.
By adding "earlycon" in GRUB in a modified JeOS-hikey image I get:
EFI stub: Booting Linux Kernel...

This was reproducible with a next-20170523 kernel and there was resolvable by
enabling CONFIG_PINCTRL_SINGLE=y.
On master branch we already have CONFIG_PINCTRL_SINGLE=m, so I fear we will
need to change that to =y.
