I am not sure if I get your point. The Armada-398 extends the
Armada-395 about 2 additional SATA ports (as you can see in commit
"[PATCH 15/18] ARM: mvebu: a398: update the dtsi about missing
interfaces"). In this example the a398-db board contains the Armada398
SoC, so it is a better match and goes first.

Quite the same is for existing armada-388-db.dts, in which compatible
looks like this:
compatible = "marvell,a385-db", "marvell,armada388",
"marvell,armada385", "marvell,armada380";

In above, Armada-388 also extends the Armada-385 and the order of the
compatible is similar to one from my example.

Thank you,
Grzegorz
