Message : Add an option to copy the artifact to vendor partition Add a --copy-to-vendor-partition optional argument to both roll_aosp.sh and generate_android_bp.py. When specified the root targets will be generated with vendor: true and a relative install path to egl folder, so that we can use ANGLE as the Android OpenGLES driver when the system starts up. Test: run roll_aosp.sh --copy-to-vendor-partion, build the Android image with m -j72, load the image with the Android emulator and find all ANGLE related *.so's are under the /vendor/lib/egl folder. Bug: angleproject:5456 Change-Id: I38c64e8ea3ad5f5d0cc0b8cd77856f49109b23c7 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2568907 Commit-Queue: Tim Van Patten <timvp@google.com> Reviewed-by: Tim Van Patten <timvp@google.com>
