# U-boot build supports producing a object files to the separate external

# directory. Two use cases are supported:

#u-boot支持将目标文件生成在外部文件夹中，以下两种命令可以实现

# 1) Add O= to the make command line

#1 加入o=命令

# 'make O=/tmp/build all'

# 2) Set environement variable BUILD_DIR to point to the desired location

# 2 设置环境变量

# 'export BUILD_DIR=/tmp/build'

# 'make'

# The second approach can also be used with a MAKEALL script

# 'export BUILD_DIR=/tmp/build'

# './MAKEALL'

# Command line 'O=' setting overrides BUILD_DIR environent variable.

# When none of the above methods is used the local build is performed and
