[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.
