/* Set the partitions to access the chip addresses
 *
 * To simplify driver code, a fixed (virtual) memory map is defined for
 * register and memory addresses. Because in the chipset, in different stages
 * of operation, those addresses will move around, an address translation
 * mechanism is required.
 *
 * There are four partitions (three memory and one register partition),
 * which are mapped to two different areas of the hardware memory.
