[U-Boot] How to generate an interrupt from u-boot

Hi,

Iam working on the samsung smdkv310 based soc. I want to generate an interrupt from the timer. Is it possible to service an interrupts at u-boot level. Smdkv310 board is having the GIC controller. Is there any patches to initialise the GIC(Generic interrupt controller).

Please do needful.

Thanks balaji
