How to get multi-sources from GIT server

You can assign a name to distinguish the different GIT URIs, and define different destsuffix to save them respectively. Furthermore, to override SRCREV with the name, you can assign different commit id for each GIT branch.

SRC_URI = " \
    git://git.allseenalliance.org/gerrit/core/alljoyn.git;protocol=https;branch=${GIT_BRANCH};name=router;destsuffix=git/core/alljoyn \     
    git://git.allseenalliance.org/gerrit/services/base.git;protocol=https;branch=${GIT_BRANCH};name=services;destsuffix=git/services/base \
    file://modify_flags_for_yocto.patch"
SRCREV_router = "0d71b216bb3a3cadc615c3eda6f8200093c5e117"
SRCREV_services = "403cda579242701d42d2d7c0da308d63a8f46070"
