The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
This is work in progress!

How to close Trac issues automatically via email
It searches commit messages for text in the form of: * command #1 * command #1, #2 * command #1 & #2 * command #1 and #2
You can have more then one command in a message. The following commands are supported. There is more then one spelling for each command, to make this as user-friendly as possible.
* closes, fixes The specified issue numbers are closed with the contents of this commit message being added to it. * references, refs, addresses, re The specified issue numbers are left in their current status, but the contents of this commit message are added to their notes.
A fairly complicated example of what you can do is with a commit message of:
Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12.
This will close #10 and #12, and add a note to #12.
- Contributed code must be GPL'd (preferrably GPLv2 or any later version), or at least have a GPL-compatible license.

Verbatim copy from the Linux kernel (we might modify this a bit):
To improve tracking of who did what, especially with patches that can percolate to their final resting place in the kernel through several layers of maintainers, we've introduced a "sign-off" procedure on patches that are being emailed around.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as a open-source patch. The rules are pretty simple: if you can certify the below:
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or
(b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or
(c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.
(d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
then you just add a line saying
Signed-off-by: Random J Developer <firstname.lastname@example.org>
Some people also put extra tags at the end. They'll just be ignored for now, but you can do this to mark internal company procedures or just point out some special detail about the sign-off.
