This option adds support for ATA controllers with SFF
compliant or similar programming interface.
SFF is the legacy IDE interface that has been around since
the dawn of time. Almost all PATA controllers have an
SFF interface. Many SATA controllers have an SFF interface
when configured into a legacy compatibility mode.

Silicon Image 3124, or Marvell 6440, you may choose to
disable this uneeded SFF support.
