Hi,
Few comments on the .dts data layout below.

The board .dts file should include the omap3 SoC .dts file.
The omap3 SoC .dts file should have the devices mapped to L3 and L4
busses, and the then i2c@1 would just contain the bus offset.
Then the i2c@1 entry would be repeated in the board specific
.dts and tell that the i2c@1 is enabled.

There's no GIC on omap3, that's only on Cortex A9 systems.
