[U-Boot-Users] Addresses in Multi-File Image

[Alemao]

Hi,

I have a multi-file image (kernel + ramdisk + dtb), and for booting im using:

=> bootm ${kernel_addr} ${ramdisk_addr} ${fdt_addr}

But for getting theese addrs from the multi-file imgage i had to
browse with an hex editor. Im
sure thats the "dumb way". Is there any tool for doing that? Or
command in u-boot prompt?

In the bottom of this link:
http://www.denx.de/wiki/DULG/RootFileSystemInAReadOnlyFile
, there is a topic called: Kernel with a Flattened Device Tree Blob.
This is exactly what im doing, but
this example doesnt show how to use bootm with the image.

Thanks,
