Very cool! I'll try testing this with Armada XP dev board DB-MV784MP-GP.

As far as I remember, mvgbe with Armada XP is using a kind of compatibility mode that makes the ethernet interface behave as in earlier Marvell SoCs. Officially the way mvgbe work with Armada is not supported by Marvell (that's why these registers aren't described in the manual). The original Armada XP port that I committed to CVS did not have ethernet driver at all. It was kiyohara@ that later added the mvgbe support for Armada XP.
