[PATCH 3/4] ARM: mvebu: move DT Dove to MVEBU

From: sebastian.hesselbarth@gmail.com (Sebastian Hesselbarth)
Date: 2014-02-27 21:28:57
Also in: linux-devicetree, lkml
Subsystem: arm and arm64 soc sub-architectures (common parts), arm port, arm/marvell dove/mv78xx0/orion soc support, arm/marvell kirkwood and armada 370, 375, 38x, 39x, xp, 3700, 7k/8k, cn9130 soc support, generic phy framework, the rest · Maintainers: Arnd Bergmann, Krzysztof Kozlowski, Alexandre Belloni, Linus Walleij, Russell King, Andrew Lunn, Sebastian Hesselbarth, Gregory Clement, Vinod Koul, Linus Torvalds

With all the DT support preparation done, we are able to move Dove
to MVEBU easily. Legacy non-DT mach-dove is left untouched to rot
for a while before removal. Also, convert SATA PHY Kconfig entry,
which is DT-only.
