  *
  *  Theory of operation
  *
- *  The driver is initialized through platform_device.  Structures which
- *  define the configuration needed by the board are defined in a
- *  board structure in arch/ppc/platforms (though I do not
- *  discount the possibility that other architectures could one
- *  day be supported.
+ *  The driver is initialized through of_device. Configuration information
+ *  is therefore conveyed through an OF-style device tree.
  *
  *  The Gianfar Ethernet Controller uses a ring of buffer
  *  descriptors.  The beginning is indicated by a register
