+/* All of our structures, like pci resource, have 32 bit members.
+ * Drivers are expected to do an ioremap on the PCI MEM resource, but it's
+ * hard to store 0x4 0000 0000 in a 32 bit type. We require a small patch
+ * to __ioremap to check for addresses between (u32)Au1500_PCI_MEM_START and
+ * (u32)Au1500_PCI_MEM_END and change those to the full 36 bit PCI MEM
+ * addresses. For PCI IO, it's simpler because we get to do the ioremap
+ * ourselves and then adjust the device's resources.
