Indeed if initramfs is not built-in vmlinux/uImage then kernel command-line
must be adjusted to point to real root device.
This could be done in 2 ways:
[1] Manually modify "bootargs" value in arch/arc/boot/dts/axs10{1|3}.dts
[2] In case of U-Boot it's possible to load device tree blob together with uImage
and in that case U-Boot's "bootargs" env variable will override the one in .dtb
