We just trust them :) Are these files from the architecture independent portion of glibc or are they csky specific? If they are architecture independent, we might want to see if they make sense for other architectures as well, and add them to lib/ rather than arch/csky/lib/ Should the SPDX identifier list the original LGPL-2.1 license instead of GPL-2.0?
