> From: Christopher Larson <chris_larson at mentor.com>
> Please review the following changes for suitability for inclusion. If you
> have
> any objections or suggestions for improvement, please respond to the
> patches. If
> you agree with the changes, please provide your Acked-by.
> This only implements support for shallow mirror tarballs, not shallow
> clones.
> The mirror tarball filename includes branch, revision, and depth. To
> enable,
> use the `BB_GIT_SHALLOW` variable, or `BB_GIT_SHALLOW_<name>` for specific
> URLs. This variable can hold either a clone depth (e.g. `1` to just get
> SRCREV), or a ref or commit, in which case we keep history up to that
> commit.
> The shallow support will not, at this time, function correctly for
> linux-yocto, due to its branching scheme & validation.
> Example:
>     BB_GIT_SHALLOW ?= "1"
>     BB_GIT_SHALLOW_pn-linux-yocto = ""
>     BB_GIT_SHALLOW_pn-linux-mel_mx6 = "v3.14"
>     BB_GIT_SHALLOW_pn-testrepo = "testbranch"
> This implementation will attempt to fetch a full mirror tarball if it was
> unable to fetch a shallow tarball. If `BB_GIT_SHALLOW` and
> `BB_GENERATE_MIRROR_TARBALLS` are enabled for a given recipe, a shallow
> tarball will be emitted.

I forgot to mention, this implements [YOCTO #7958](
