Add omap4 soc dts file for handling omap4 soc i2c
controllers existing on l4-core bus.
The subject and changelog is not accurate. You are doing at least 3 things:
Moving the OMAP4 SoC data from panda board file to a SoC specific
omap4.dtsi file.
Including the omap4.dtsi into panda.
Adding some i2c nodes.
You should use at least two or three separated patches to avoid
in-accurate subject.

That information was already there previously but where does it come from?
48 MB is clearly not for the FB, and the top 256 MB should be accessible
with highmem.
