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'
57#
58# The second approach can also be used with a MAKEALL script
59# 'export BUILD_DIR=/tmp/build'
60# './MAKEALL'
61#
62# Command line 'O=' setting overrides BUILD_DIR environment variable.
63#
64# When none of the above methods is used the local build is performed and
65# the object files are placed in the source directory.
