I've had a little intrest in the OMAP3 support for the BeagleBoard-xM and Gumstix Overo boards. I will leave it in for now and remove only the Tegra 2 code. For people interested in either of these boards, or another OMAP3 board I would suggest you start working on bringing the support up to a level where we can boot on these boards otherwise the code will come up for removal again.
