+/**
+ * @page devinfo_command
+
+If called without arguments, devinfo shows a summary of the known
+devices and drivers.
+
+If called with a device path being the argument, devinfo shows more
+default information about this device and its parameters.
+
+Example from an MPC5200 based system:
+
+@verbatim
+ barebox:/ devinfo /dev/eth0
+ base : 0x1002b000
+ size : 0x00000000
+ driver: fec_mpc5xxx
+
+ no info available for eth0
+ Parameters:
+ ipaddr = 192.168.23.197
+ ethaddr = 80:81:82:83:84:86
+ gateway = 192.168.23.1
+ netmask = 255.255.255.0
+ serverip = 192.168.23.2
