Welcome to Renesas R-Car H1
rcar login:
------------------
Can anyone let me know, whether I need to modify the kernel config to
support systemd ? I am aware of systemd kernel config dependencies and
IMX6 Linux-3.10 boots and mounts fines on same "systemd" based rootfs,
but not the R-Car H1.
Thanks,
Srikanth
