Is the PCI-interrupt map that part of the dts file :

                interrupt-map = <

                        /* IDSEL 0x02 */
                        1000 0 0 1 &mpic 1 1
                        1000 0 0 2 &mpic 2 1
                        1000 0 0 3 &mpic 3 1
                        1000 0 0 4 &mpic 4 1

                        /* IDSEL 0x03 */
                        1800 0 0 1 &mpic 4 1
                        1800 0 0 2 &mpic 1 1
                        1800 0 0 3 &mpic 2 1
                        1800 0 0 4 &mpic 3 1

			...

I do not understand anything there :(
