Should include the soc in this compatible list: compatible = "samsung,smdkv310", "samsung,s5pv310"; Also, every 'compatible' value specified in this file should also have documentation in Documentation/devicetree/bindings. > + #address-cells = <1>; > + #size-cells = <1>; It's usually a good idea to have a "interrupt-parent = <&GIC>;" here so that all child nodes inherit it as the default interrupt controller. Also, missing a 'cpus' node. > + > + memory { > + device_type = "memory"; > + reg = <0x40000000 0x08000000>; > + }; > + > + chosen { > + bootargs = "root=/dev/ram0 rw ramdisk=8192 initrd=0x41000000,8M > console=ttySAC1,115200 init=/linuxrc"; initrd base address will get passed via the linux,initrd-start and linux,initrd-end properties which are automatically populated by u-boot.

I assume the wdt in the s5pv310 is compatible with the one in the s3c2410, correct?
