Thanks for your reply, but this firmware can find the rootfs itself,

This is too late - as this is the MTD partition info provided from kernel's DTB.
You need the root= information which is probably available on your environment (not accessible by some reason from new u-boot).
BTW: What is the version of old u-boot ?
