[U-Boot] [PATCH v5 03/13] buildman: Allow building of current source tree
Simon Glass
sjg at chromium.org
Fri Aug 8 13:10:20 CEST 2014
Originally buildman had some support for building the current source tree.
However this was dropped before it was submitted, as part of the effort to
make it faster when building entire branches.
Reinstate this support. If no -b option is given, buildman will build the
current source tree.
