- * @mainpage Usage
- *
- * @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.
