I would recommend that you make your root #address-cells and #size-cells equal
to 2, as that will simplify matters later if/when you need to add anything
beyond the first 4GB for some particular board.

If everything in the SoC falls within the first 4GB you can have a ranges
property on your /soc node and have only one cell below that.

The unit-address doesn't match the first address in the reg entry.

Shouldn't the virtual CPU interface also be 0x2000 long?
