Where is the code you are referencing above? This is the "old" bd_t style of booting. Only the boot wrapper code or and old kernel would still be using this.

the code is from arch/powerpc/boot/cuboot-bamboo.c, and the kernel is 2.6.30.1, the boot image I'm using is something like cuImage.bamboo, I checked zImage.ld.S, and found that when we're running cuImage.bamboo, we actually fall into arch/powerpc/boot/crt0.S:_zimage_start(), which will call platform_init() and then bamboo_init() finally. but sounds like if we passing r3 as fdt, then the code (platform_init, etc.., and even arch/powerpc/kernel/head_xxx.S start() function, only comments, though) is actually wrong, isn't it? Thank you very much for help.
This is the boot wrapper code only used if you are trying to boot a new kernel w/an old u-boot. If you are using a current u-boot you should just be using a plain old uImage as produced by the kernel build.
