# The following three variables:
# conf_git
# conf_branch
# conf_external
#
# are used to retrieve kernel config fragments from an external source tree
# in git.linaro.org.
# The URL where the files are taken is built in this way:
# http://git.linaro.org/gitweb?p=$conf_git;a=blob_plain;f=linaro/configs/$conf;hb=$conf_branch
# conf_git: is the git tree where to look into, like landing-teams/working/arm/kernel.git
# conf_branch: is the branch to use, like HEAD
# conf_external: is a comma separated list of kernel config file names to retrieve, it is
# possible to list also only one file name
#
# An example of usage of these variables:
# conf_git='landing-teams/working/arm/kernel.git'
# conf_branch='HEAD'
# conf_fragment='android.conf,imx5.conf'
