arm/dts: Add minimal device tree support for omap2420 and omap2430
Add minimal device tree support for omap2420 and omap2430. This is needed to keep the uart functional on omap2 after omap_serial_init is removed from board-generic.c. Reviewed-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
