===== coreboot release checkout =====

If you don't clean git submodules when checking out a new stable release, your resulting build will be tagged as "dirty". Follow these steps to avoid this.

Generate gitconfig:

<code bash>
make gitconfig
</code>

Check out the new release: 

<code bash>
git pull
git checkout 4.18
</code>

Destroy submodules:

<code bash>
git sup-destroy
</code>
