 Here the ICU device for `/tty@0` is `/icu@0` (device at address 0x20600000), which in turn references `/cpus/Mips,32@0` as its ICU device.
+
+== The /chosen node ==
+
+The `/chosen` node contains informations about the global system peripherals and configuration. In MutekH, we use the `/chosen` node to reference preipherals:
+ `timer`::
+  Select the global timer device
+ `root`::
+  Select the root file system device
+ `console`::
+  Select the console tty
+
+Referencing the correct devices does not implicitly make their drivers available. You still have to select the driver in your configuration file.
+
+Example:
+{{{
+        chosen {
+                console = &{/tty@0};
+                root = &{/ramdisk@0};
+        };
+}}}
