device tree?
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
