    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
    driver to using platform-device. I got a reply, that it's not worth it now
    that IDE is slowly becoming obsolete, and the pata_platform serves the
    perpose perfectly well. I found this argument reasonable, I had the same
    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?

    Thanks
