From 9e84ed63dc71e13b62cea5ec6b0049260cca0b7a Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 9 Sep 2010 22:39:41 +0100 Subject: [PATCH] ARM: Partially revert "Auto calculate ZRELADDR and provide option for exceptions" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Partially revert e69edc7, which introduced automatic zreladdr support. The change in the way the manual definition is defined seems to be error and conflict prone. Go back to the original way we were handling this for the time being, while keeping the automatic zreladdr facility.
