Hello Hans,
I have been wrestling with the u-boot for BananaPi R1 (Lamobo R1) for
some time . As you have mentioned and I have also seen , many people are
working on this board , but not too many have attempted to submit
patches up stream . I am attaching to this email a patch , which
combines work of many people such as Igor P - armbian , Zoltan H -
openwrt , and others who have scattered their scripts over the internet
. I believe that within the patch we have the important information
captured for the Lamobo R1 board : SATA power , IR , GMAC . As you can
see the dts has evolved from the original bananapi which it uses for
basis , and additional bits were put on . I do not know the original
revision of the bananapi dts , but I can see that it differs a lot form
the current one in terms of structure . I wanted to attempt to re-write
it to make it closer to the current one , but was sure that I would
brake it , if I did . I leave it to your skill . Since I have a couple
of these boards , I am happy to test any mods for you .
Best Regards
Milorad
