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. Signed-off-by: Enric Balletbo i Serra <eballetbo@iseebcn.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
