How to setup interrupts for a new board?

["Ardelean, Andrei" <Andrei.Ardelean@idt.com>]

Hi,

I created new board specific files gd_xxxx similar with malta_xxxx and I
am trying to configure Linux interrupts in gd-int.c.
My board has no external interrupt controller like Malta has, it has no
PCI, I use Vectored interrupt mode and a mux routes the external
interrupts to the MIPS h/w interrupts.
Wthat is the meaning of the following switches and how to set them:
cpu_has_divec            
cpu_has_vce             
cpu_has_llsc
cpu_has_counter
cpu_has_vint

What is the difference between:
setup_irq()
set_irq_handler()
set_vi_handler()

Can you point me to document regarding interrupts implementation in MIPS
Linux?

Thanks,
Andrei
