+Freescale Layerscape Debug Server Support:
+-------------------------------------------
+The Freescale Layerscape Debug Server Support supports the loading of
+"Debug Server firmware" and triggering SP boot-rom.
+This firmware often needs to be loaded during U-Boot booting.

+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.
