linux-toradex.git/arch/powerpc/boot/div64.S, branch v3.4.2 Linux kernel for Apalis and Colibri modules powerpc/boot: Add extended precision shifts to the boot wrapper. 2011-12-09T12:49:27+00:00 Tony Breeds tony@bakeyournoodle.com 2011-11-30T21:39:21+00:00 e32a03290c72773c304ffeebffed0a63c0a672ae The upcomming currituck patches will need to do 64-bit shifts which will fail with undefined symbol without this patch. I looked at linking against libgcc but we can't guarantee that libgcc was compiled with soft-float. Also Using ../lib/div64.S or ../kernel/misc_32.S, this will break the build as the .o's need to be built with different flags for the bootwrapper vs the kernel. So for now the easyest option is to just copy code from arch/powerpc/kernel/misc_32.S I don't think this code changes too often ;P Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Josh Boyer <jwboyer@gmail.com>

powerpc: Move ppc64 boot wrapper code over to arch/powerpc 2005-11-16T02:52:21+00:00 Paul Mackerras paulus@samba.org 2005-11-16T02:38:21+00:00 94b212c29f685ca54b5689a8e89ac7671c43d651 This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines). Signed-off-by: Paul Mackerras <paulus@samba.org>
