# dahdi-linux claims to be GPLv2 with parts LGPLv2.1 (not 'or later'),
# but there are the so-called firmware files (downloaded above) for
# which the license is unclear: the header claims to be GPLv2, the
# 'loader-wrapper' claims to be GPLv2, but there are two so-called
# 'firmware' binary-only .o blobs for which the license is not
# explicited, which look like they end up as part of a kernel module,
# and for which the source is nowhere to be found on the upstream site
# (they are only for x86/x86_64, but we still list them unconditionally).
