Dear Sergey Lapin,

Tom is right when asking to use a stable kernel tree version as starting point. Said "interesting changes" may be added in a second step, once we have proven that the stable code is actually working stable for us, too.
OK, will rebase.
Well, I reviewed the difference with 3.7.1 and 3.8-rc's MTD, and I see some changes I critically depend on. These are very small, though. The rest can be added for completeness. I can make these changes into separate patch, will it be fine with you?
Ideally you should come up with a workign implementation based on the current stable tree. The locate any additional commits in Linux that are needed / useful from your point of view, and check if these can be applied _directly_ (i. e. the unmodified Linux commits) to the U-Boot tree. If we can do this, any future updates will be much easier, so this is a good test for the benefits of the new version.
Well, direct application of Linux's commits will not work mostly because lower level functions like timers have slightly different implementations. If we'd implement jiffies and associated macros in u-boot, that'd be awesome, but maybe an overkill, and is also out of scope of these patches and not in field of my interests. Simple things, like constant changes will work, but code changes in nand_base.c won't work I'm afraid.
Best regards,
Wolfgang Denk
