Yes, you are right. Sorry for not mention that in the patch.

Yes, the IGEPv2 and the Overo are indeed very similar machines so we
base the hardware modeling on the Overo.

The only differences here are which OMAP version is used to initialize
the MPU (3630 instead of 3430) and the NAND memory used, Numonyx
OneNAND instead of Micron NAND.

What is the benefit to have yet another OMAP3 device? Well.. I don't know ;-)

We just add this device model for our clients so I thought it was a
good idea to post the patch upstream. But feel free to ignore me if
you think that it doesn't add any value to Linaro QEMU.

Sorry about that, I didn't know that GPLv2 or later was the norm in
the QEMU project.

Also, is good to notice that the Versatile Express board
(hw/vexpress.c) and the StrongARM emulation support (hw/strongarm.c)
also use GPLv2-only license. If you need to fix those too.

Thanks a lot and best regards,
Javier
