[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. Signed-off-by: Deepak Saxena Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
