Switch the ColdFire head start up code to be in the .text.head segment. And make sure that segment is at the start of the final linked text segment. Fixes the linker warnings about section use mis-matches: WARNING: vmlinux.o(.text+0xa8): Section mismatch in reference from the variable _clear_bss to the function .init.text:start_kernel() The function _clear_bss() references the function __init start_kernel(). This is often because _clear_bss lacks a __init annotation or the annotation of start_kernel is wrong. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
