69# U-boot build supports producing a object files to the separate external
70# directory. Two use cases are supported:
71#
72# 1) Add O= to the make command line
73# 'make O=/tmp/build all'
74#
75# 2) Set environement variable BUILD_DIR to point to the desired location
76# 'export BUILD_DIR=/tmp/build'
77# 'make'
78#
79# The second approach can also be used with a MAKEALL script
80# 'export BUILD_DIR=/tmp/build'
81# './MAKEALL'
