Hello,
The Marvell Armada 38x ARM processors use an AHCI compatible interface
for SATA (in replacement of the Marvell-specific SATA interface,
handled by the sata_mv driver). However, like all DMA-capable Marvell
interfaces, some specific MBus window configuration must be done, so a
small specific glue layer is needed, which relies on the recently
introduced libahci_platform.c.
The first patch of this series contains the driver itself, which is
fairly straight-forward. It should be taken by Tejun Heo as the ATA
maintainer.
The last three patches add the Device Tree and defconfig changes. They
should be taken by the respective ARM maintainers (mvebu maintainers
for the DT and mvebu_v7_defconfig, and arm-soc maintainers for the
multi_v7_defconfig change).
This series is currently based on linux-next. If this is a problem for
merging, I'll resend a new version once 3.15-rc1 lands.
Thanks!
Thomas
