Patch submission

The development of MCUboot takes place in the MCUboot GitHub repository.

To submit patches, use GitHub pull requests.

Each commit has to have, in the commit message, a “Signed-off-by” line that mentions the author (and the committer, if that is different). You must add this line at the end of the commit text, separated by a blank line. You can also add a line linking the commit to a specific GitHub issue, as this section supports multiple lines, similarly to RFC-2822.

The supported trailer lines are structured as follows:

A line that indicates that the signer agrees to the “Developer Certificate of Origin” located at the bottom of this page:
```
    Signed-off-by: Developer Name <devname@example.com>
```
A line that links this commit to specific GitHub issues, if present:
```
Keyword #GH_issue_number
```
For more details about linking a GitHub pull request to a GitHub issue, see this [link] (https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue).

Release notes

To facilitate creating release notes at release time, all non-trivial changes must include a release note snippet in the pull request. This can be either a separate commit, or as part of a single commit (generally, if there are multiple commits to the pull request, the release note snippet should be a separate commit, and a pull request that is a single commit can include the release note snippet in that commit). In either case, the release notes must be included in the same PR that makes the given change.

The release notes should be placed in the docs/release-notes.d directory. Please see the readme file in that directory for specifics.
