Hi,

Not 100% sure, but anyway...

Can you recheck after squashing all memory nodes to a single one.

I guess, you have following in your device tree:

memory@48000000 {
device_type = "memory";
/* first 128MB is reserved for secure area. */
reg = <0x0 0x48000000 0x0 0x38000000>;
};

memory@500000000 {
device_type = "memory";
reg = <0x5 0x00000000 0x0 0x40000000>;
};

memory@600000000 {
device_type = "memory";
reg = <0x6 0x00000000 0x0 0x40000000>;
};

memory@700000000 {
device_type = "memory";
reg = <0x7 0x00000000 0x0 0x40000000>;
};

Try to make next:

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>;
};
