From da90d4ce386d0481c2e772624dfc32e511829238 Mon Sep 17 00:00:00 2001 From: Albert Aribaud Date: Tue, 5 Oct 2010 16:06:39 +0200 Subject: [PATCH] arm: bugfix: replace ble with blo in start.S files Generalized misuse of ble within relocation and bss initialization loops caused one iteration too many. Instead of ble ('branch if lower or equal'), use blo ('branch if lower'). While we're at it, fix all 'addreee' typos.
