Provide SRM 1.3 kernel packages, extracted from Synology GPL Source archives.
original archives are about 1.8 GB and downloaded from:
https://archive.synology.com/download/ToolChain/Synology%20NAS%20GPL%20Source/1.3-9346
The archives of the required kernel sources are about 90 MB.
The kernel files contain a part (the linux-* folder) of the gpl source archives and are created like this:
for arch in cypress dakota hawkeye ipq806x; do
echo "Create ${arch}-linux-4.4.x.txz"
mkdir -p synogpl-9346-${arch}
cd synogpl-9346-${arch}
sudo tar -xjpf ../synogpl-9346-${arch}.tbz
cd source
tar -cJf ../../${arch}-linux-4.4.x.txz linux-4.4.x
cd ../..
done
