Respect SOURCE_DATE_EPOCH when building FIT images.
Embedding timestamps in FIT images results in unreproducible builds for targets that generate a fit image, such as dra7xx_evm. This patch uses the SOURCE_DATE_EPOCH environment variable, when set, to use specified value for the date. Thanks to HW42 for debugging the issue and providing the patch: https://lists.alioth.debian.org/pipermail/reproducible-builds/Week-of-Mon-20160606/005722.html For more information about reproducible builds and the SOURCE_DATE_EPOCH specification: https://reproducible-builds.org/specs/source-date-epoch/ https://reproducible-builds.org/ Signed-off-by: Vagrant Cascadian <vagrant@debian.org> Reviewed-by: Simon Glass <sjg@chromium.org>
