device tree interrupt-map/interrupt-map-mask properties for a 405EP board

Hi,
I am trying to setup a device tree for a 405EP based board.
I did not fully understand how to setup the interrupt-map-mask and
interrupt-map properties for the PCI node:
...
PCI0: pci@ec000000 {
...
interrupt-map-mask = <0x???? 0x0 0x0 0x0>;
interrupt-map = <
/* slot1: IDSEL AD12 - ext. Irq 4 */
0x???? 0x0 0x0 0x0 &UIC0 29 0x8
/* slot2: IDSEL AD13 - ext. Irq 5 */
0x???? 0x0 0x0 0x0 &UIC0 30 0x8
/* slot3: IDSEL AD14 - ext. Irq 6 */
0x???? 0x0 0x0 0x0 &UIC0 31 0x8
>;
};
I have three PCI slots on the board. How do I have to fill out the ???? fields
above? ADxx <-> IDSEL connection can be taken from the comments. Each slot
has its interrupt lines INTA..D connected to a single 405 external interrupt
input.
Where can I find any docs about this?
