[Arm-netbook] HDMI v1.4 Audio Return and Ethernet channels

[Richard Wilbur]

Luke,

Have you considered using the Audio Return channel in HDMI v1.4 to
send digital multi-channel sound back to the EOMA68-A20?  How about
the Ethernet channel (also in HDMI v1.4)?

Does the processor support these?  They are optional capabilities of
HDMI v1.4 and I only ask because it would change the routing.

Sincerely,
Richard
