Dear Kyungmin Park,
I've now used your patch series to add UBI support to the i.MX31 Litekit board (in the NAND device present on that board) and have some additional comments on the series.
2008/10/28 Kyungmin Park kmpark@infradead.org:
Now you can use the UBI at apollon board

I had some problems that boiled down to the fact that the unused fields of mtd_part caused problems in add_mtd_partitions(). Doing a memset(&mtd_part, 0, sizeif (mtd_part)) before the mtd_part.name line solved those problems.
