# The tarball for this package can be re-created from the upstream
# repository with the following commands:
#   $ PN=u-boot PV=2013.07 P=${PN}-${PV}
#   $ git clone git://git.denx.de/${PN}.git ${P}
#   $ cd ${P}
#   $ git checkout v${PV}
#   $ rm -rf .git
#   $ cd ..
#   $ tar cf ${P}.tar ${P}
#   $ bzip2 ${P}.tar
#
# TODO(jrbarnette):  Really, we want to eliminate this ebuild
# altogether, and rely on the standard Chromium OS U-Boot ebuild.
