From 0365f707c99bf940a51c2a3ffc19f3ade2f700d4 Mon Sep 17 00:00:00 2001 From: Jesper Nilsson Date: Tue, 21 Oct 2008 22:10:27 +0200 Subject: [CRIS] Merge asm-offsets.c for both arches into one file. Eliminates the link to arch specific asm-offsets.c from CRIS architecture build system. Resulting asm-offsets.s are identical before and after change for both arch-v10 and arch-v32.

Changed $(ARCH) to "cris" in Makefile, it is easier to read this way. The CRISv32 head.S common files for the kernel and compressed images needed to be modified to use ifdefs instead of using the now removed mach link. Since there are only two versions, this is not a huge loss in readability. The link to vmlinux.lds.S is also replaced with a merged version which uses ifdefs to select the correct layout. System.map before and after are identical.
