86 * Virtual memory map for the Intel IXP12X0 integrated devices
87 *
88 * IXP12x0 processors have many device registers at very lower addresses.
89 * To make user process space wider, we map the registers at lower address
90 * to upper address using address translation of virtual memory system.
91 *
92 * Some device registers are staticaly mapped on upper address region.
93 * because we have to access them before bus_space is initialized.
94 * Most device is dinamicaly mapped by bus_space_map(). In this case,
95 * the actual mapped (virtual) address are not cared by device drivers.
