If I use "chrpboot " bootloader, I have to provide many functions in my boot codes according to CHRP specifications: 1 "prom"(promptr) functions which can provide with "/chosen" ,"claim" and "getprop" services etc in arch/ppc/chrpboot/start.c and in arch/ppc/kernel/prom.c . 2 device-trees for my custom board. Are these functions all necessary for booting the linux kernel? And do I have to modify arch/ppc/mm/init.c=>MMU_init() and arch/ppc/kernel/setup.c=>identify_machines() to suit my cases? I notice that in identify_machines(), there are many types initializations functions such as pmac_init(),prep_init(),chrp_init(),apus_init(), oak_init(),m8xx_init(),m8260_init(). Do I have to provide my own ***_init() functions? Thank you very much. machael ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
