parse_mtd_partitions - parse MTD partitions : the master partition (describes whole MTD device) : names of partition parsers to try or NULL : array of partitions found is returned here : MTD partition parser-specific data

This function tries to find partition on MTD device . It uses MTD partition parsers, specified in . However, if is NULL, then the default list of parsers is used. The default list contains only the "cmdlinepart" and "ofpart" parsers ATM. Note: If there are more then one parser in , the kernel only takes the partitions parsed out by the first parser.

This function may return: o a negative error code in case of failure o zero if no partitions were found o a positive number of found partitions, in which case on exit will point to an array containing this number of &struct mtd_info objects.
