Almost perfect. However:

1. All mtd patches should have "mtd:" prefix.
2. Add some description about what you do and why into the commit
message.
3. I think combining is not good, better do it old way - first patch
introduces the flag, second uses it in OneNAND

Sorry for being picky, but I really want to show you how to send patches
properly once and later get good series from you.
