[Arm-netbook] Crowsupply update

[Richard Wilbur]

I am sorry if any of my comments came across with any flavour of criticism.  I meant none towards anyone but myself.

Thank you for the pointer to the Allwinner A20 documentation.  I didn't know how easily available it was.

I was just wondering whether there were more GPIO lines we could test (by hook or by crook).  My goal is the best test coverage.

No complaints about the EOMA specification or your design decisions on the microdesktop case.
