OK, so yesterday I solved this puzzle - it was stupid pilot error (my
ubldr.bin was not built with fdt support), after fixing it I made a
test today - building SD image from scratch. It is succesfull now, so
it's time to do kernel hacking. u-boot-orangepi port needs some review
and cleanup before submitting into port repository, but anybody
interested could write me for more details.
