vmlinx and ppcboot

If I has ppcboot working and has a vmlinux.gz, do I need any other
working boot code from the kernel tree? I mean, if my making a linux
kernel image 'make zImage' fails at the last step (building a zvmlinux),
is the vmlinux.gz image built valid for ppcboot to boot the kernel?

Thanks.
