Memory nodes got duplicated somehow. Likely U-Boot did something incorrect.

Try to use single memory node in your device-tree instead of separated 
by each bank nodes:
memory@48000000 {
        device_type = "memory";
        /* first 128MB is reserved for secure area. */
        reg = <0x0 0x48000000 0x0 0x38000000>,
              <0x5 0x00000000 0x0 0x40000000>,
              <0x6 0x00000000 0x0 0x40000000>,
              <0x7 0x00000000 0x0 0x40000000>;
};
