-Use of git submodules in coreboot
-=================================
-coreboot uses git submodules to keep certain parts of the tree separate,
-with two major use cases:
-
-First, we use a vendor tool by NVIDIA for systems based on their SoC
-and since they publish it through git, we can just import it into our
-tree using submodules.
-
-Second, lots of boards these days require binaries and we want to keep
-them separate from coreboot proper to clearly delineate shiny Open Source
-from ugly blobs.
-Since we don't want to impose blobs on users who really don't need them,
-that repository is only downloaded and checked out on explicit request.
-
-Handling submodules
--------------------
-For the most part, submodules should be automatically checked out on the
-first execution of the coreboot Makefile.
-
-To manually fetch all repositories (eg. when you want to prepare the tree
-for archiving, or to use it without network access), run
-
-    $ git submodule update --init --checkout
-
-This also checks out the binaries below `3rdparty/`
-
-Mirroring coreboot
-------------------
-When running a coreboot mirror to checkout from, for full operation, you
-should also mirror the blobs and nvidia-cbootimage repository, and place
-them in the same directory as the coreboot repository mirror.
-
-That is, when residing in coreboot's repository, `cd ../blobs.git`
-should move you to the blobs repository.
-
-With that, no matter what the URL of your coreboot repository is, the
-git client (of a sufficiently new version) is able to pick up the other
-repositories transparently.
-
-Minimum requirements
---------------------
-git needs to be able to handle relative paths to submodule repositories,
-and it needs to know about non-automatic submodules.
-
-For these features, we require git version 1.7.6.1 or newer.
