[fedora-arm] F22 works great on PcDuino3 Nano

Wed Aug 26 14:47:21 UTC 2015

Just noticed this has been sitting my drafts file for a while

Everything is working now on PcDuino3_Nano, except for initial setup
scripts.  I'm not sure why.  After I get things booted up (by removing the
startup links for the initial setup stuff) I am able to run them by hand.

Image used: Fedora-LXDE-armhfp-23-20150815-sda.raw.xz
Kernel: 4.2.0-0.rc5.git0.2.fc23

Boots into a graphical LXDE desktop, correct resolution, network works.  I
currently haven't found anything that doesn't work but I have not done
extensive testing.

I'll try a newer image to see if the initial setup scripts are working  ...
but it might be a week before I get the time.
