The surrounding context looks like this:
localbus@f1000000 {
#address-cells = <2>;
#size-cells = <1>;
compatible = "mrvl,lbc";
/* This reflects CPU decode windows setup. */
ranges = <0x0 0x0f 0xf9300000 0x00100000
0x1 0x1e 0xfa000000 0x00100000
0x2 0x1d 0xfa100000 0x02000000
0x3 0x1b 0xfc100000 0x00000400>;
nor@0,0 {
#address-cells = <1>;
Specifying ranges here is a Marvel-SoC-specific thing, other arm socs
don't require it. The Marvell code uses these values to set up hardware
memory mapping; on the Marvell chips it's possible to map DRAM, NAND,
PCIe, etc into physical address ranges of your choosing.
