From 2df96b34aae08e0aa688ef7a8444febb8ec44172 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 13 Jan 2006 20:51:46 +0000 Subject: [PATCH] [ARM] 3259/1: remove phys_ram from struct machine_desc (part 1) Patch from Nicolas Pitre This field is redundent since it must be equal to PHYS_OFFSET anyway. First, let's use PHYS_OFFSET directly instead.
