/*
 * 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 I/O, it's simpler because we get to do the ioremap
 * ourselves and then adjust the device's resources.
