-Subject: [PATCH] Reproducible U-Boot build support, using SOURCE_DATE_EPOCH
-
-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.

-+Reproducible builds
-+-------------------
-+
-+In order to achieve reproducible builds, timestamps used in the U-Boot build
-+process have to be set to a fixed value.
-+
-+This is done using the SOURCE_DATE_EPOCH environment variable.
-+SOURCE_DATE_EPOCH is to be set on the build host's shell, not as a configuration
-+option for U-Boot or an environment variable in U-Boot.
-+
-+SOURCE_DATE_EPOCH should be set to a number of seconds since the epoch, in UTC.
