So I've looked into this more closely, and after drawing a diagram of
all the register areas, I came up with a much more reduced area, with
only networking related registers: starting at 0x129000 for a size of
0xb000. So now the DT node looks like this:

+                       cpm_ethernet: ethernet at 0 {
+                               compatible = "marvell,armada-7k-pp22";
+                               reg = <0x0 0x100000>, <0x129000 0xb000>;

This will be part of my next iteration.

Thanks!

Thomas
