+
+ The ranges describing the MBus windows have the following layout:
+
+ 0x8t000000 s 0 MBUS_ID(w, a) 0 1 0
+
+ where:
+
+ * t is the type of the MBus window (as defined by the standard PCI DT
+ bindings), 1 for I/O and 2 for memory.
+
+ * s is the PCI slot that corresponds to this PCIe interface
+
+ * w is the 'target ID' value for the MBus window
+
+ * a the 'attribute' value for the MBus window.
+
+ Since the location and size of the different MBus windows is not fixed in
+ hardware, and only determined in runtime, those ranges cover the full first
+ 4 GB of the physical address space, and do not translate into a valid CPU
+ address.
