The DTB file is a device tree file. It defines the memory map for the board. From what I can tell, its specific to PowerPC.

Thank you for reply.

then. The kernel only need to kown dtb file to know a board devices. such as i2c,PCI,usb, ans so on..

If I change or modify the board device, I only edit the dtb file. isn't it?

You need change source of .dtb. You need find .dts in kernel source.
