64# U-boot build supports producing a object files to the separate external
65# directory. Two use cases are supported:
66#
67# 1) Add O= to the make command line
68# 'make O=/tmp/build all'
69#
70# 2) Set environement variable BUILD_DIR to point to the desired location
71# 'export BUILD_DIR=/tmp/build'
72# 'make'
73#
74# The second approach can also be used with a MAKEALL script
75# 'export BUILD_DIR=/tmp/build'
76# './MAKEALL'
77#
78# Command line 'O=' setting overrides BUILD_DIR environent variable.
