Success building Orange Pi PC Plus (aka OPiPC+) using crochet

[Curtis Villamizar]

FYI-

I have a build using crochet for Orange Pi PC Plus that works fine.

Instructions are at http://occnc.com/info/arm64/NOTES.html

There are some contributions to crochet but I'm not sure what the
right way is to submit patches and additions to crochet is.

I added a bug report to add the sysutils/u-boot-orangepi-pc-plus port
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227506

The rest is crochet related.  I added a new crochet board directory.

One kernel bug that causes a panic at startup was worked around by
disabling the mixer/codec in a dts file but that bug seems to be
reported twice already so no sense piling on.

btw- I have a pair of Orange Pi One boards on order and will try that
when I get those.

The HDMI is not working so you need to use a serial console.
