Hi,friends,

I　made follow define on my MPC8360EMDS.h file. Is it enough? The uboot still did not fill the zero frequency on dtb. I think the ft_cpu_setup and ft_board_setup function have been run.


/* pass open firmware flat tree */
#define CONFIG_OF_FLAT_TREE	         1
#define CONFIG_OF_BOARD_SETUP	1
/* maximum size of the flat tree (8K) */
#define OF_FLAT_TREE_MAX_SIZE	8192
