48 # U-boot build supports generating object files in a 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 environment variable BUILD_DIR to point to the desired location
55 # 'export BUILD_DIR=/tmp/build'
56 # 'make'
