I've been hacking to see if I can get FreeBSD to boot on this little
device, and I got to this:

This is my github:
https://github.com/tomtor/freebsd/tree/tc2
which contains also some commits from Andrew Turner (his early RPI3 port)
and some preliminary Pine64 work (waiting for a board).
A script to build an image:
https://github.com/tomtor/image-freebsd-c2/blob/master/build/mkc2image.sh
I'm currently stuck because I cannot get a working Timer, interrupts are
for some reason not generated or get lost, so the boot hangs on an msleep
late in the boot process. I have no S905 documentation, only S805 docu,
which looks valid, except for the 64bit arm difference.
The guys at
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145457216438&tab_idx=2
are
still waiting for the datasheet :-/
What I noticed is that Timer-E is somehow not running, Timer-A works as
expected (I can see it counting in the debugger), except perhaps for the
interrupts.
If someone has suggestions how to fix this, cq hints how to proceed, that
would be very nice!
