I'm a bit confused: 'do_irq' is defined in several files, including
CPU-specific (arm920t, 720t etc.) and ARM architecture library
($(U_BOOT)/lib_arm). So if we build for arm920t-based platform
(provided that CONFIG_USE_IRQ is defined), then which one will be
actually compiled in resulting image?

Thanks.
