+ * 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.
