This is now very similar to pata_platform.c, they both use

To achieve that, byte_lanes_swapping platform data variable

since those were never used anyway.

pata_platform and ide_platform are carrying same driver names,
to easily switch between these drivers, without need to touch
platform code.

Why? There's a drivers/ide/arm/ide_arm.c IDe driver that some platforms

exists?

    Good question (I know the answer but won't tell ;-).
