From: Enric Balletbo i Serra <eballetbo at iseebcn.com>
The IGEP v2 board is a low-cost, fan-less and industrial temperature
range single board computer that unleashes laptop-like performance and
expandability without the bulk, expense, or noise of typical desktop
machines. Its architecture shares much in common with other OMAP3 boards.
