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 (not
in the mainline) hack to access, e.g., CF cards in true-IDE mode. About a
month ago I submitted a patch to arm-linux-kernel switching that

Not entirely. The patch (or other patches in the series) would also touch ARM platforms in the mainline, currently using that driver. As I didn't

Was worth cross-posting to linux-ide anyway to get the IDE experts' feedback. ;-)

that IDE is slowly becoming obsolete, and the pata_platform serves the

It was largely in accordance with my own opinion, so, I chose to accept it:-)

doubt, just wanted to double-check. So, why do we now need a new legacy
(a/drivers/ide/legacy/ide_platform.c) driver when a "modern" driver exists?

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

You've been very cooperative, thanks.

   In fact, I also highly doubt that we need it.  What we'd need is an OF driver.

Thanks
