Can't use it if the pin has no connection to the CPU!

In the last screenshots I saw (
http://hands.com/~lkcl/eoma/a20_hdmi_review/scrn2.png ), pin 2 HEAC+
(ethernet/ARC) is not connected to anything. Pin 1 (HEAC- & HPD) does go
somewhere, but it's of no use for these functions by itself.

CEC does seem to be routed and is mentioned on the A20 info page.

No SBC that I've seen actually uses these functions (unfortunately).
