2         reg = <0 0xffe09000 0 0x1000>;

3          ranges = <0x2000000 0x0 0xa0000000 0 0xa0000000 0x0 0x20000000 //everything is clear for me

4                          0x1000000 0x0 0x00000000 0 0xffc10000 0x0 0x10000>; //everything is clear for me

5           pcie@0 {

6                   ranges = <0x2000000 0x0 0xa0000000 //phys.hi+ phys.mid +phys.low

7                                    0x2000000 0x0 0xa0000000 //I dont know what means

8                                  0x0 0x20000000                    //I dont know what means


10                                 0x1000000 0x0 0x0             //phys.hi+ phys.mid +phys.low

11                                 0x1000000 0x0 0x0         //I dont know what means
