It's not yet covered. it's TODO

Anyway, here's UBI patch.
The real implementation was done by another board but to publish I
make a patch for apollon board for usage. (tested and verified)

As see it's all-in-one patch and contains several parts, apollon
board, OneNAND, mtdpartition, and UBI.

After the feedback, I will generate right patches for purpose.

Please give any comments and feedbacks

Thank you,
Kyungmin Park

P.S., it's bzip2ed since mailing list has size limitation.
