Sitecom WLM-4600 support

Hello, I am asking here as I intend to compile openWRT for the Sitecom WLM-4600.

Unfortunately, this device has the quite infamous RT63365/RT63368F, but I think there should still be a way around this. In particular, I was able to binwalk some current data, as well as gain root shell on the device and hence the dumps of /proc. I have uploaded these dumps here.

Please let me know if anyone can help me on where to start. I have tried adding support by editing the makefile in target/linux/ramips and creating this folder, but then compilation fails because I need a .dts file. Can anyone help me on this one?
Thank you
