ARM: at91: add defconfig for device tree (2012-04-17 14:47:22 +0200)

----------------------------------------------------------------
First batch of AT91 cleanup for 3.5 kernel.
- The biggest improvement of this series is the ability to compile several AT91 SoCs in one kernel image.
For now on it's limited to the DT-enabled boards but we can compile all the core together.
- The Kconfig series is stacked before other patches as it is simple and non-intrusive. Its goal is to remove too restrictive dependencies on SoC names. This will allow to add support for newer SoC seamlessly.
- Some very "cosmetic" Kconfig changes are also added (entry names, comments, etc.).

Bye,

Nicolas Ferre

Pulled into the next/cleanup branch, and also pulled the MAINTAINERS update into the next/maintainers branch.

Olof, this is the first pull from a tag I've done, and I think we should decide on a method to show these pulls in the log. I've set the at91/cleanup branch to the version that Nicolas sent, without the merge changeset that is normally generated when you pull from a tag. For next/cleanup branch, I've pulled directly from the tag and edited the commit message a bit. Do you think that's good or do you know a better way to handle these?

Arnd

Short version:

That sounds like a good way to handle it, and it's similar to how I did things for the last cycle.

Long version:

There, I had this workflow:

* git fetch <url+branch from pull request>
* tig FETCH_HEAD (look at contents, sanity check, etc: If something
looks wrong there's no merge to undo)
* git checkout -b subarch/topic FETCH_HEAD to create the pulled-in
topic branch
* git checkout next/topic
* git pull --log <url+branch from pull request> to get the original
URL in the merge commit

Then the usual steps to get it into for-next and added to the contents file.

That way we do get the --log in the next/ branch as well as the tag message, but only one merge changeset. It also has the benefit of making it trivial to see when things have been merged with mainline which branches can be pruned and not.

The only thing missing from that workflow is the authenticity of the subarch/topic branch once it's done, in case there is tinkering with the arm-soc repo by some third party. I don't think that's a big risk since we tend to diff the for-next contents before and after a rebuild, so any delta in file contents will be caught. Since each branch is documented in arm-soc-for-next-contents, we should have all bases covered there.

I guess we could tag every subarch/topic tip as well, but it'll get pretty noisy with all them in the main repo. We have the option of pushing those to a separate repo instead of the main arm-soc.git if we wanted though.

-Olof

Ok. I've now started skipping the 'checkout -b' step and just doing a 'git branch subarch/topic FETCH_HEAD', but the result is the same.

I also catch changes to the branches when I update my tree.

The idea I've had before is to just keep tags for each subarch/topic instead of branches, which would seperate them from one another, and we could leave the message in the tag without it cluttering the history.

The main disadvantage I see in that is that I don't have a good workflow for maintaining remote tags yet.
