[Buildroot] RFC [PATCH v2 0/3] scmversion tracking for linux and uboot

[Charles Hardin]

Adding source control tracking into the linux and uboot packages
specifically.

The generic problem is that buildroot needs to make reproducible tarballs
for verification which means the ".git" directories have to be excluded
from the archive since they can change even though the contents from the
git reference has not changed.

This leads to the problem that a setlocalversion script will not
work in the build because after the extract there is no access to the
history information given the reasons above.

To mitigate this problem and allow change control tracking for local
development and remote references a somewhat intruisive change needs to
be introduced at the download step for the archive to add an scmversion
during the creation when both the revision history in the source tree
exists and the archive is being created.

Charles Hardin (3):
  support/download: add a helper scipt to generate scmversions
  boot/uboot: add a scmversion rsync hook when overriding srcdir
  linux: add a scmversion rsync hook when overriding srcdir
