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.
Changes since v1:
* Rebased on top of v3.15-rc1
* Added a preliminary patch that orders alphabetically the list of
compatible strings in the DT binding document
ahci-platform.txt. Suggested by Andrew Lunn.
* Made the availability of MBus DRAM window informations
mandatory. Suggested by Andrew Lunn.
* Fixed the module alias name. Suggested by Bartlomiej
Zolnierkiewicz.
Details of the patches:
* The first patch is a DT binding documentation cleanup. I believe it
should be taken by the ATA maintainer, because the second patch
(driver patch) depends on it.
* The second 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).
Thanks!
Thomas
