From f1a1b63529986d0c8970da182f0935eae059421b Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 8 Jul 2014 09:17:16 +0200 Subject: [PATCH] m68k: Fix boot regression on machines with RAM at non-zero My enhancement to store the initial mapping size for later reuse in commit 486df8bc4627bdfc032d11bedcd056cc5343ee62 ("m68k: Increase initial mapping to 8 or 16 MiB if possible") broke booting on machines where RAM doesn't start at address zero. Use pc-relative addressing to fix this.
