From bfe4375a1a184c2145ef235e782660400b005882 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 15 Nov 2011 14:12:01 +1000 Subject: m68k: define PAGE_OFFSET_RAW for ColdFire CPU with MMU enabled The ColdFire CPU configurations need PAGE_OFFSET_RAW set to the base of their RAM. It doesn't matter if they are running with the MMU enabled or disabled, it is always set to the base of RAM. We can keep the choices simple here and key of CONFIG_RAMBASE. If it is defined we are on a plaftorm (ColdFire or other non-MMU systems) which have a configurable RAM base, just use it.
