As long as we distinguish Allwinner naming convention from what is inside we shall be fine (although Allwinner tries hard to confuse people... as if ARM had not done enough :) ) That being said I think support for Allwinner chips is worth being continued. They are cheap, quite robust, quite popular, and documentation is reasonably available (credits go to sunxi I must admit) So enough talking, time to go down to basement, disconnect my old Olimex-A10-Lime and try to put FreeBSD on it. I do expect troubles as I am not convinced it will work out of the box (e.g. it is A10 but I can see there is A20_cpu_cfg (dual core) among files.allwinner, which does not sound right to me...). However I also see that some good soul put more sources in compare to 10.2 tree.
