49 # U-boot build supports producing a object files to the separate external
50 # directory. Two use cases are supported:
51 #
52 # 1) Add O= to the make command line
53 # 'make O=/tmp/build all'
54 #
55 # 2) Set environement variable BUILD_DIR to point to the desired location
56 # 'export BUILD_DIR=/tmp/build'
57 # 'make'
58 #
59 # The second approach can also be used with a MAKEALL script
60 # 'export BUILD_DIR=/tmp/build'
61 # './MAKEALL'
62 #
63 # Command line 'O=' setting overrides BUILD_DIR environent variable.
