ARM: omap1: remove osk-mistral add-on board support
Browse files Browse the repository at this point in the history 
As Aaro Koskinen points out, nobody should have this one any more,
and I noticed the code is rather ugly, so let's removed it but
keep the rest of the OSK support that is still used.

The OSK supports an optional add-on board with a Quarter-VGA
touchscreen, PDA-ish buttons, a resume button, bicolor LED,
and camera connector. Say Y here if you have this board.
