Hi, I am using customized ppc440 based board. We have created a .dtb file, u-boot should not update the file because of that we have added following macro in config file #define CONFIG_OF_LIBFDT 1 #undef CONFIG_OF_BOARD_SETUP With the above change kernel code gets hang with following log:
Movable zone start PFN for each node early_node_map[1] active PFN ranges 0: 0x00000000 -> 0x00030000 MMU: Allocated 1088 bytes of context maps for 255 contexts Built 1 zonelists in Zone order, mobility grouping on.

When we debug the u-boot code by added the following flag #define CONFIG_OF_BOARD_SETUP 1 Kernel works fine. Is there any dependency of CONFIG_OF_BOARD_SETUP flag for .dtb file?
