To clarify my earlier comment, I think it would be nicer to write this as
ranges =
<0x82000000 0 0x40000 0xffff0001 0x40000 0 0x00002000
0x82000000 0 0x80000 0xffff0001 0x80000 0 0x00002000
0x82000000 1 0 MBUS_ID(0x12, 0x34) 0 1 0
0x82000000 2 0 MBUS_ID(0x13, 0x34) 0 1 0
0x81000000 1 0 MBUS_ID(0x12, 0x35) 0 0 0x10000;
0x81000000 2 0 MBUS_ID(0x13, 0x35) 0 0 0x10000>;
The MBUS_ID numbers above are made up since I don't know them, but this way you can
describe how the entire 4GB MMIO address space of the PCI bus is mapped into the
MBUS address space.

Then you do a ranges property for each port with the high-order
address word equal to the port number:
ranges = <0x82000000 1 0 0x82000000 0 0 1 0
0x81000000 1 0 0x81000000 0 0 0 0x10000>;

ranges = <0x82000000 2 0 0x82000000 0 0 1 0
0x81000000 2 0 0x81000000 0 0 0 0x10000>;

Does this make sense?
