+ * If the IDE controller is in legacy mode, pci_setup_device() fills in
+ * the resources with the legacy addresses that normally appear on the
+ * PCI bus, just as if we had read them from a BAR.
+ *
+ * However, with the GT-64111, those legacy addresses, e.g., 0x1f0,
+ * will never appear on the PCI bus because it converts memory accesses
+ * in the PCI I/O region (which is never at address zero) into I/O port
+ * accesses with no address translation.
+ *
+ * For example, if GT_DEF_PCI0_IO_BASE is 0x10000000, a load or store
+ * to physical address 0x100001f0 will become a PCI access to I/O port
+ * 0x100001f0. There's no way to generate an access to I/O port 0x1f0,
+ * but the VT82C586 IDE controller does respond at 0x100001f0 because
+ * it only decodes the low 24 bits of the address.
+ *
+ * When this quirk runs, the pci_dev resources should contain bus
+ * addresses, not Linux I/O port numbers, so convert legacy addresses
+ * like 0x1f0 to bus addresses like 0x100001f0. Later, we'll convert
+ * them back with pcibios_fixup_bus() or pcibios_bus_to_resource().
