Subject[PATCH v3 04/12] ata: ahci_mvebu: add support for Armada 3700 variant
Date
From: Lior Amsalem <alior@marvell.com>

The main difference in the new Armada 3700 is that no address
decoding needs to take place in the driver probe.

[gregory.clement@free-electrons.com: reformulate the commit log]
