This is out of date now?

It would be great to get this sorted as per my prior comments.. Maybe
like this is easy?
pcie-controller {
compatible = "marvell,armada-370-xp-pcie";
// Index by marvell,pcie-port ?
regs = <0xd0040000 0x00002000
0xd0080000 0x00002000>;
ranges = <0x81000000 0 0 0xc0000000 0 0x00010000 /* downstream I/O */
0x82000000 0 0 0xc1000000 0 0x08000000>; /* non-prefetchable memory */
pcie at 0,0 {
device_type = "pci";
reg = <0x0800 0 0 0>; // 00:01.0 (????)
marvell,pcie-port = <0>;
};
}
It is abusive to map the device internal per-port registers through
'0x00000800 0 0xd0040000' and 'reg' - that is not really the intent of
the OF spec.
