+ * Note about PCI IO space mappings

+ * To make IO space accesses efficient, we store virtual addresses in
+ * the IO resources.
+ *
+ * The PCI IO space is located at virtual 0xfe000000 from physical
+ * 0x90000000. The PCI BARs must be programmed with physical addresses,
+ * but when we read them, we convert them to virtual addresses. See
