add_mtd_device - register an MTD device : pointer to new MTD device info structure

Add a device to the list of MTD devices present in the system, and notify each currently active MTD 'user' of its arrival. Returns zero on success or 1 on failure, which currently will only happen if there is insufficient memory or a sysfs error.

del_mtd_device - unregister an MTD device : pointer to MTD device info structure

Remove a device from the list of MTD devices present in the system, and notify each currently active MTD 'user' of its departure. Returns zero on success or 1 on failure, which currently will happen if the requested device does not appear to be present in the list.

int parse_mtd_partitions	(	struct mtd_info *	master,

		struct mtd_part_parser_data *	data
	)

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.
