Subject: [PATCH v3 net-next 0/6] Support Armada 37xx SoC (ARMv8 64-bits) in mvneta driver

Hi,

The Armada 37xx is a new ARMv8 SoC from Marvell using same network
controller as the older Armada 370/38x/XP SoCs. This series adapts the
driver in order to be able to use it on this new SoC. The main changes
are:

- 64-bits support: the first patches allow using the driver on a 64-bit
  architecture.

- MBUS support: the mbus configuration is different on Armada 37xx
  from the older SoCs.

- per cpu interrupt: Armada 37xx do not support per cpu interrupt for
  the NETA IP, the non-per-CPU behavior was added back.

The first item is solved by patches 1 to 3.
The 2 last items are solved by patch 4.
In patch 5 the dt support is added.

Beside Armada 37xx, the series have been tested on Armada XP and
Armada 38x (with Hardware Buffer Management and with Software Buffer
Managment).

Thanks,

Gregory
