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.
