Easy question, easy answer: When it's ready!  And that depends on
how many people are actively working on it.  And that depends on,
well, basically on how many people are interested in ARM and have
enough spare time to work on it.  That number isn't quite high.

There's plenty of hardware, but it's all crap.  I say that without
actually knowing all hardware.  But I know, because my limited
experience told me it's the same as in the 32-bit ecosystem.

The raspberryPi 3 would be the first 64-bit platform we might support,
running a 32-bit kernel.  One could do the same for other harware, but
most of them are China crapware and as soon as you wrote the first
driver there will be a next generation of that chip and the old one
is garbage.

So far every Allwinner hardware feels the same.  I have a PineA64.  I
ran it once with linux and then packed it back into the box.  I did the
same with the Qualcomm 410c, which seems a bit better though.  I just
found out I can run u-boot on it (instead of fastboot), which is a lot
better than fastboot alone.

What we need is stable hardware that has proper documentation and is
properly upstreamed.  That's a combination that isn't often found in
the ARM ecosystem.  Especially the PineA64 was completely rushed.

I think the Dragonboard might actually be helpful to bootstrap OpenBSD
on ARM64, but otherwise it's not really useful.  The rPi3 can do that,
too.  I have my eyes on bigger, but more expensive, hardware.


At least those have chips that are supposed to be used in servers and
not tablets.
