In order to achieve reproducible builds in U-Boot, timestamps that are defined at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment variable allows setting a fixed value for those timestamps. Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be built reproducibly. This is the case for e.g. sunxi devices. However, some other devices might need some more tweaks, especially regarding the image generation tools. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>

# We are using a recursive build, so we need to do a little thinking
|
|
# to get the ordering right.
|
|
#
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
# their own directory. If in some directory we have a dependency on
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
# after that we are sure that everything which is in that other dir
|
|
# is now up to date.
|
|
#
|
|
# The only cases where we need to modify files which have global
|
|
# effects are thus separated out and done before the recursive
|
|
# descending is started. They are now explicitly listed as the
|
|
# prepare rule.
