\
G=C3=BCnter> uImage
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.
G=C3=BCnter> This file is bootable, but I don't understand how a standard
G=C3=BCnter> file has to be booted.
With an external dtb / initrd.
G=C3=BCnter> Can someone explain me the different fileforamts for booting
G=C3=BCnter> a powerpc with u-boot? Which is the simplest to use?
Have a look at Documentation/powerpc/bootwrapper.txt
