[PATCH 1/2] ARM: OMAP3: Add support for the IGEP v2 board (rev B)

[PATCH 1/2] ARM: OMAP3: Add support for the IGEP v2 board (rev B)

[Enric Balletbò i Serra]

This patch adds minimal IGEP v2 support.

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.

Re: [PATCH 1/2] ARM: OMAP3: Add support for the IGEP v2 board (rev B)

[Tony Lindgren]

* Enric Balletbò i Serra <eballetbo@gmail.com> [091014 01:48]:
> This patch adds minimal IGEP v2 support.

Can you please refresh against the for-next branch in linux-omap and
repost?

Thanks,

Tony
