First, while I appreciate the effort, I'd rather us sync with v3.7 release rather than the in-flux v3.8. Second, can you please look at the archives about how we've done these re-syncs before? I really don't want to take a single giant patch and we're usually able to break this up into chunks. Thanks!

It's like with out of tree code: If you're out of tree, you don't exist. If the patches have not been posted here, they don't get reviewed here, i. e. they don't exist. Best regards, Wolfgang Denk

Thanks! current v3.8 version is not that much different from v3.7, and very few, but interesting changes there, so I hope we're not going for version numbers here. I try to produce proper splitted version, but it is not going to be bisectable then. > > -- > Tom

Can you elaborate on these interesting changes please?

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. > I try to produce proper splitted version, but it is not going to be > bisectable then. I cannot see why this would have to be the case. Bisectability has to be maintained. Best regards, Wolfgang Denk

Well, if you mean, by bisectable, that it will compile, then yes, it can be done, but I still can't find a way to properly split patch for it to obey to reasoning behind bisect, in this case. All the best, S.

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. Best regards, Wolfgang Denk

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 > > -- > DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd@denx.de > Let's say the docs present a simplified view of reality... :-) > - Larry Wall in <6940@jpl-devvax.JPL.NASA.GOV>

Thanks! Can someone point to the exact thread where such discussion has happened before? The re-sync has to happen addressing the bisect-ability as well. Already there was a discussion on syncing the UBI layer. So, if some ideas are thrown, it would be beneficial for both MTD and UBI sync. Thanks, Vikram

So, if some > ideas are thrown, it would be beneficial for both MTD and UBI sync. What I was thinking of was: http://en.usenet.digipedia.org/thread/11185/23221/ http://en.usenet.digipedia.org/thread/11185/23218/ http://en.usenet.digipedia.org/thread/11185/28371/ But, from a lazy-poke of a single file, once we get out from the includes section of the files, some git format-patch'ing on the files we share with the kernel, between the last backport hash and v3.7 for example should be applicable with only a bit of hand fixing up. And if one wanted to do this slowly (3.0 to 3.1 to 3.2 to ...) it might be a little easier to manage.
Hi, all! As I failed to submit 250KB patch to the list I will send this pull request This patch is not for inclusion yet. This patch is just update of u-boot MTD with Linux kernel's MTD v3.8-rc.
