it should be pretty apparent (since many fsl boards and some amcc 4xx have all necessities already).

Normally,
+#define CONFIG_OF_LIBFDT 1
+#define CONFIG_OF_BOARD_SETUP 1
+#define OF_CPU "<your CPU node>"

should be enough, if you CPU family have necessary fdt hook-ups, or you may need add a few lines to
BSP code.
