I believe we should really have a generic way to probe ATA
ports as long as they are compatible to the standard register
set, and use a generic of-ata driver for that. The two
questions arising there are:
1. Should there be a new device-type for ATA? Alternatively
we would only look at the "compatible" property, maybe
looking for a generic "ata" name.
2. How do we make sure the of-ata driver and the specific
(e.g. sata_fsl) driver don't fight over the same devices?
Would it be enough to reject all known specific devices
in of_ata_probe?
