sata_mv: Support SoC controllers
Marvell's Orion SoC includes SATA controllers based on Marvell's PCI-to-SATA 88SX controllers. This patch extends the libATA sata_mv driver to support those controllers. [edited to use linux/ata_platform.h -jg] Signed-off-by: Saeed Bishara <saeed@marvell.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
