Ok, my patch is bogus. It doesn't even let me do what I wanted.
*smacks self for not testing first*

The real issue is that my kernel entry point is not fixed. The entry
point can be found by searching for the 'kernel_entry' symbol in the
vmlinux. And unfortunately, I can't search for this at an appropriate
time to be able to set UBOOT_ENTRYPOINT.

What I would need is something like the following, post do_compile.

UBOOT_ENTRYPOINT=`${NM} ${S}/vmlinux | \
		awk '$3=="${UBOOT_ENTRYSYMBOL}" {print $1}'

Where UBOOT_ENTRYSYMBOL="kernel_entry" could be set from the ${MACHINE}.conf.


Presumably no one else's machine with a variable entry point is using
u-boot.... The uImage makefile target in my kernel tree generates a
uImage anyway. Perhaps this step could simply be skipped if the
${S}/arch/${ARCH}/uImage file already exists?
