From 7086e91b0e9930139e703c8f9f857b52baf2bef4 Mon Sep 17 00:00:00 2001 From: Benoît Thébaudeau Date: Thu, 11 Apr 2013 09:35:46 +0000 Subject: arm: relocate_code(): Use __image_copy_end for end of relocation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).
