This option enables limited support for the Marvell 88SE6145 ATA
controller.
This option enables limited support for the Marvell 88SE61xx ATA
controllers. If you wish to use only the SATA ports then select
the AHCI driver alone. If you wish to the use the PATA port or
both SATA and PATA include this driver.
If unsure, say N.
