You could also make it an of_platform_driver at the same time
instead of adding more cruft to fsl_soc.c. Since we're already
about to add the electra_ide.c driver in 2.6.23, I guess there
should really be _one_ driver that is able to handle all
of_device based ATA hosts.

and do so using libata. Preferably ata_platform but it does look like
ata_of would make sense as a companion.

I wouldn't push for it too much tho. It's perfectly fine to have
"helpers" generate xx_platform from the device-tree. Since I added the
generic dev_archdata to struct device, it's easy for the arch to keep
track of OF devices for anything, it doesn't have to be an of_platform
device or anything like that anymore.

One of the things I have in mind is to provide a way to register
"constructors" that are based on an OF match set. Those would then be
called by the arch code for every OF node that matches, and would then
"construct" the appropriate linux device. Could be some kind of platform
device, could even be PCI devs.
