If the commit you wish to update is the most recent +commit you have made, after making your desired changes, stage the files +(either using git add or in git cola), and amend the commit. To do so, +if you are using the command line, run "git commit --amend." If you are +using git cola, click on the gear icon located on the upper left side under +**Commit** and select **Amend Last Commit** in the drop down menu. Then, stage +the files you have changed, commit the changes, and run git push to push the +changes to the remote repository. Your change should be reflected in Gerrit as +a new patch set. + +If, however, the commit you wish to update is not the most recent commit you +have made, you will first need to checkout that commit. To do so, find the +URL of the commit on <https://review.coreboot.org> and go to that page; if +the commit is one that you previously pushed, it can be found by selecting +**My** and then **Changes** in the upper left corner. To checkout this commit, +in the upper right corner, click on **Download**, and copy the command listed +next to checkout by clicking **Copy to clipboard**. Then, run the copied +command in your coreboot repository. Now, the last commit should be the most +recent commit to that patch; to update it, make your desired changes, stage +the files, then amend and push the commit using the instructions in the above +paragraph.
