The PCI device table in the powermac IDE driver isn't properly
terminated. Depending on how your kernel is linked and other random
factors, you can end up with this driver matched against any other PCI
device in your system, possibly crashing at boot.

Hi,

The built-in IDE controller is configured in legacy mode,
but the PCI registers advertise native mode.
Force the PCI class into legacy mode. This allows pata_via to access
two drives.

reg-shift alone isn't enough to know how to access the device
registers. In the case of UARTs, they typically are internal
to some SoC, so the device driver can just look up what SoC it
is and will then know what to do. For IDE though, as far as I

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

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
