From 17d82fcc6a15887b7138d35802ab8fc5f249794f Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Fri, 3 Jun 2005 22:18:52 +0100 Subject: [PATCH] ARM: 2700/1: Disable IXP2000 IRQs at bootup Patch from Deepak Saxena The IXDP2800 bootloader does not disable IRQs before jumping into the kernel and this is causing the Grand Unified KGDB to crash the system when we do an early call to trap_init() and irq handlers have not yet been registered. This patch disables IRQs before we jump into the kernel.
