Improve compilation speed for android build
Currently FFTF python script is used for creating flashfiles.zip. It uses ZipWrite python api which is time consuming and adds overhead to build time. Say, flash.json generation, unpacking of target files, installer.cmd generation, etc. This fix helps to optimize build time and involves below changes: - Use tar + pigz combo for faster flashfiles generation. - Make FFTF a bash script as python doesn't directly support tar + pigz - Add use_tar=true flag to "make flashfiles" to enable it. e,g, "make flashfiles -j<N> use_tar=true" - The new script still supports all old functionalities, say, generation of installer.cmd, flash.json, repacking of bootloader.img, etc. Tracked-On: OAM-112083 Signed-off-by: sgnanase <[email protected]> Signed-off-by: Chen, Gang G <[email protected]>
