Parititions can overlap, even with DT, but you just need to make sure
that node addresses are unique, such that if you want to make
overlapping partitions of this kind:
firmware@30000 {
reg = <0x30000 0x10000>;
name = "firmware";
};
rootfs@30001 {
reg = <0x30000 0x2000>;
};
Since both firmware and rootfs start at the same offset, you still
need them to have an unique node name if you want the MTD OF parser to
be able to parse *both* of them.
