* Partition definition structure:
*
* An array of struct partition is passed along with a MTD object to
* add_mtd_partitions() to create them.
*
* For each partition, these fields are available:
* name: string that will be used to label the partition's MTD device.
* size: the partition size; if 0, the partition will extend to the end of the
* master MTD device.
* offset: absolute starting position within the master MTD device; if 0,
* partition will start where the previous one ended.
* mask_flags: contains flags that have to be masked (removed) from the
* master MTD flag set for the corresponding MTD partition.
* For example, to force a read-only partition, simply adding
* MTD_WRITEABLE to the mask_flags will do the trick.
*
* Note: writeable partitions require their size and offset be
* erasesize aligned.
