+When using the MAKEALL script, the default behaviour is to build U-Boot
+in the source directory. This location can be changed by setting the
+BUILD_DIR environment variable. Also, for each target built, the MAKEALL
+script saves two log files (<target>.ERR and <target>.MAKEALL) in the
+<source dir>/LOG directory. This default location can be changed by
+setting the MAKEALL_LOGDIR environment variable. For example:

+With the above settings build objects are saved in the /tmp/build, log
+files are saved in the /tmp/log and the source tree remains clean during
+the whole build process.
