What I mentioned was how it can be handled when we mount rootfs directly fr=
om kernel.

1) kernel -> initramfs (mount root) -> systemd
2) kernel (mount root) -> systemd
 -> In this case, we normally use root=3D/dev/sda1 from kernel commandline =
to mount the rootfs.

Like fstab can support legacy node mount, ufs driver also needs to provide =
an option for using the permanent legacy node. If you're really worry about=
 adding a new codes for all UFS driver, we can put this as controller speci=
fic or optional feature.
