bitbake: fetch/git: add support for removing arbitrary revs for shallow
In certain cases, it's valuable to be able to exert more control over what history is removed, beyond srcrev+depth. As one example, you can remove most of the upstream kernel history from a kernel repository, keeping predominently the non-publically-accessible content. If the repository is private, the history in that repo couldn't be restored via `git fetch --unshallow`, but upstream history could be. Example usage: # Remove only these revs, not at a particular depth BB_GIT_SHALLOW_DEPTH_pn-linux-foo = "0" BB_GIT_SHALLOW_REVS_pn-linux-foo = "v4.1" (Bitbake rev: 97f856f0455d014ea34c28b1c25f09e13cdc851b) Signed-off-by: Christopher Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
