- * As per PCI spec, ignore base address registers 0-3 of the IDE controllers

- * secondary channels respectively). If the device reports Compatible mode

- * Exceptions (if they exist) must be handled in chip/architecture specific
- * fixups.
- *
- * Note: for non x86 people. You may need an arch specific quirk to handle
- * moving IDE devices to native mode as well. Some plug in card devices power
- * up in compatible mode and assume the BIOS will adjust them.
- *
- * Q: should we load the 0x1f0,0x3f4 into the registers or zap them as
- * we do now ? We don't want is pci_enable_device to come along
- * and assign new resources. Both approaches work for that.
