  48 # U-boot build supports producing a object files to the separate external
  49 # directory. Two use cases are supported:
  50 #
  51 # 1) Add O= to the make command line
  52 # 'make O=/tmp/build all'
  53 #
  54 # 2) Set environement variable BUILD_DIR to point to the desired location
  55 # 'export BUILD_DIR=/tmp/build'
  56 # 'make'
