MTD RAID

[Dongsheng Yang]

Hi David, Boris, Richard, Artem,

     Thanx for your suggestions, after a second thinking, I will 
consider to put
the RAID layer top on ubi, that sounds better, although we have some 
specified
problems if we don't build RAID device on MTD layer. I will send another 
email
about this topic later if I have a decision to move RAID layer on ubi or 
not.

Thanx a lot
Yang
