Hello,
I'am looking for an image to boot a embedded device with a single image.
I though the generated uImage in arch/powerpc/boot should work, but =
u-boot cannot but this,
because the addresses of initrd and dtb not found.
Now I'am creating the image by hand with mkimage:
mkimage -A ppc -n F302 -O linux \
-T multi -C gzip -a 0x0 -e 0x0 \
-d vmlinux.bin.gz:initramfs_data.cpio.gz:f302.dtb \
uImage
This file is bootable, but I don't understand how a standard file has to =
be booted.
I read in th u-boot documentation about a new fileformat which is build =
with the dtc.
Can someone explain me the different fileforamts for booting a powerpc =
with u-boot?
Which is the simplest to use?
Shold I reconfigure u-boot?
Thanks for help

I posted a patch to add support for multi image uImages to the kernel
makefiles, E.G. uImage.<platform> some time ago. It got nack'ed by
wdenx though as he wants people to use the new fitimage stuff in
u-boot instead. Anyway, it might be useful to you:
http://peter.korsgaard.com/patches/linux/bootwrapper-uboot-multi-2.patch
To use it, add:
image-$(CONFIG_<your-platform>) + uImage.<your-platform>
to arch/powerpc/boot/Makefile.

With an external dtb / initrd.

Have a look at Documentation/powerpc/bootwrapper.txt
