      Reproducible U-Boot build support, using SOURCE_DATE_EPOCH · f3f431a7
      Paul Kocialkowski authored
      
      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.
