Hello,
As the result of implementation of https://blueprints.launchpad.net/linaro-android-infrastructure/+spec/build-c... , android-build.linaro.org now can indirectly fetch build config stored in a git repository. To achieve that, bootstrap config (as specified in android-build.linaro.org) should contain reference to config's repo/branch/file (configuration variables are modeled on the similar MANIFEST_* ones), e.g.:
BUILD_CONFIG_REPO=git://git.linaro.org/people/pfalcon/android/linaro/build-configs.git BUILD_CONFIG_BRANCH=master BUILD_CONFIG_FILENAME=panda-ics-gcc46-tilt-tracking-blob.conf
http://android.git.linaro.org/gitweb?p=linaro/build-configs.git%3Ba=summary was created to store configs for the official builds in the Gerrit tree.
Sample job is available here: https://android-build.linaro.org/builds/~pfalcon/git-build-config/ (it uses personal repo as a test).
