I'd actually say be very careful about this - there's a big difference between the ATA subsystem and IDE subsystem. I've had situations with old platforms where stuff works with IDE and not ATA. For example, using the CY82C693 driver used to work with the IDE subsystem before it got broken on ARM systems with DMA disabled (because the CY82C693 deadlocks the PCI bus on any BM-DMA). From what I remember, ATA provided no easy way to disable DMA on such interfaces. I also looked at using ATA on EBSA110, and it was far from trivial due to munged address lines and access size problems: with IDE, it was easy to work around by redirecting the in*/out* appropriately on a per-driver basis. I forget exactly why ATA didn't work, but it didn't and I came to the conclusion that it was not feasible to fix. So, please don't assume that ATA can be simply slotted in instead of IDE. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
