Thanks, I will take a look. I also made some progress. I used a
different config I found on the Banana Pi forums (availble here
http://www.fw-web.de/dokuwiki/lib/exe/fetch.php?media=bpi-r2:mt7623n_evb_ryderlee_defconfig.txt)
and while there are some errors when booting, booting to the ramdisk
works fine. So it seems that the DTS at least is not completely
broken.

BR,
Kristian
