Removing the dma-coherent flags in the dts file seemed really odd until
I read the text above. It would seem more logical to me to have a .dtsi file
that has all the a0 revision specific changes, and include that from the
dts file.
On the other hand, the /chosen, /aliases and /memory nodes that you have
in the .dtsi file should probably get moved into the .dts files, as these tend
to be board specific settings, even if the examples you have are all
the same.
