+ * initial memory mapping like legacy BAT registers do. Usually we
+ * use four MAS registers(MAS0-3) to operate on TLB1 entries.
+ *
+ * We also need LAWs(Local Access Window) to associate a range of
+ * the local 32-bit address space with a particular target interface
+ * such as PCI/PCI-X, RapidIO, Local Bus and DDR SDRAM.
+ *
+ * We put TLB1/LAW code here because memory mapping is board-specific
+ * instead of cpu-specific.
