+ * The V3 PCI interface chip in Integrator provides several windows from
+ * local bus memory into the PCI memory areas. Unfortunately, there
+ * are not really enough windows for our usage, therefore we reuse
+ * one of the windows for access to PCI configuration space. The
+ * memory map is as follows:
+ *
+ * Local Bus Memory Usage
+ *
+ * 40000000 - 4FFFFFFF PCI memory. 256M non-prefetchable
+ * 50000000 - 5FFFFFFF PCI memory. 256M prefetchable
+ * 60000000 - 60FFFFFF PCI IO. 16M
+ * 61000000 - 61FFFFFF PCI Configuration. 16M
+ *
+ * There are three V3 windows, each described by a pair of V3 registers.
+ * These are LB_BASE0/LB_MAP0, LB_BASE1/LB_MAP1 and LB_BASE2/LB_MAP2.
+ * Base0 and Base1 can be used for any type of PCI memory access. Base2
+ * can be used either for PCI I/O or for I20 accesses. By default, uHAL
+ * uses this only for PCI IO space.
+ *
+ * Normally these spaces are mapped using the following base registers:
+ *
+ * Usage Local Bus Memory Base/Map registers used
+ *
+ * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
+ * Mem 50000000 - 5FFFFFFF LB_BASE1/LB_MAP1
+ * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
+ * Cfg 61000000 - 61FFFFFF
+ *
+ * This means that I20 and PCI configuration space accesses will fail.
+ * When PCI configuration accesses are needed (via the uHAL PCI
+ * configuration space primitives) we must remap the spaces as follows:
+ *
+ * Usage Local Bus Memory Base/Map registers used
+ *
+ * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
+ * Mem 50000000 - 5FFFFFFF LB_BASE0/LB_MAP0
+ * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
+ * Cfg 61000000 - 61FFFFFF LB_BASE1/LB_MAP1
+ *
+ * To make this work, the code depends on overlapping windows working.
+ * The V3 chip translates an address by checking its range within
+ * each of the BASE/MAP pairs in turn (in ascending register number
+ * order). It will use the first matching pair. So, for example,
+ * if the same address is mapped by both LB_BASE0/LB_MAP0 and
+ * LB_BASE1/LB_MAP1, the V3 will use the translation from
+ * LB_BASE0/LB_MAP0.
+ *
+ * To allow PCI Configuration space access, the code enlarges the
+ * window mapped by LB_BASE0/LB_MAP0 from 256M to 512M. This occludes
+ * the windows currently mapped by LB_BASE1/LB_MAP1 so that it can
+ * be remapped for use by configuration cycles.
+ *
+ * At the end of the PCI Configuration space accesses,
+ * LB_BASE1/LB_MAP1 is reset to map PCI Memory. Finally the window
+ * mapped by LB_BASE0/LB_MAP0 is reduced in size from 512M to 256M to
+ * reveal the now restored LB_BASE1/LB_MAP1 window.
+ *
+ * NOTE: We do not set up I2O mapping. I suspect that this is only
+ * for an intelligent (target) device. Using I2O disables most of
+ * the mappings into PCI memory.
