From 9c8dc1a88c760ec121a260afc9583ec9239497ef Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Mon, 12 Jul 2010 15:19:04 +0900 Subject: [PATCH] ARM: S5PV210: Fix on MAX_PHYSMEM_BITS on S5PV210/S5PC110. This patch fixes on MAX_PHYSMEM_BITS for Sparsemem on S5PV210/S5PC110. Because physical memory can be located from 0x20000000 to 0x7fffffff, so MAX_PHYSMEM_BITS is 31 and not 32.
