+ * @section intro Introduction
+ * This library provides all functionality to handle with the so-called
+ * platform description data (PDD) and the bootparameters defined in
+ * U-Boot. It is able to apply the defined PDD operations in PDD update
+ * scenarios. For more information about the PDD and bootparameter
+ * environment "bootenv" confer the PDD documentation.
+ *
+ * @section ret Return codes
+ * This library defines some return codes which will be delivered classified
+ * as warnings or errors. See the "Defines" section for details and numeric
+ * values.
+ *
+ * @section benv Bootenv format description
+ * There are two different input formats:
+ * - text files
+ * - binary files
+ *
+ * @subsection txt Text Files
+ * Text files have to be specified like:
+ * @verbatim key1=value1,value2,value7\n key2=value55,value1\n key4=value1\n@endverbatim
+ *
+ * @subsection bin Binary files
+ * Binary files have to be specified like:
+ * @verbatim<CRC32-bit>key1=value1,value2,value7\0key2=value55,value1\0... @endverbatim
+ * You can confer the U-Boot documentation for more details.
+ *
+ * @section benvlists Bootenv lists format description.
+ * Values referenced in the preceeding subsection can be
+ * defined like lists:
+ * @verbatim value1,value2,value3 @endverbatim
+ * There are some situation where a conversion of a comma
+ * seperated list can be useful, e.g. to get a list
+ * of defined PDD entries.
