Subject: [PATCH 6/7] bootwrapper: allow platforms to call library zImage_start

From: Milton Miller <[email-masked]>
Date: Mon, 19 Mar 2007 14:58:05 -0600 (CST)

Some platforms might need to run some code before the zImage start, but
could otherwise use the bss clear and relocation code.   Export the
start address strongly as zImage_start_lib.
