Hello,
I have a similar problem with my custom board CPU mpc8548 (E500V2)
with
4Gbytes of RAM
0x0000_0000 -- 0x7FFF_FFFF 2Gbytes
0x1_0000_0000 -- 0x1_7FFF_FFFF 2Gbytes
I Enable the option PHYS_64BIT, and set in dts
memory {
#address-cells = <2>;
#size-cells = <1>;
device_type = "memory";
reg = <00000000 00000000 00000000 7FFFFFFF
00000001 00000000 00000000 7FFFFFFF>;
};
But the kernel can see just 2Gbytes of memory.
How the kernel can see the other 2Gbytes ?
Michele
This should be:
reg = < 0x00000000 0x00000000 0x00000000 0x80000000
0x00000001 0x00000000 0x00000000 0x80000000 >;
Its a start, size pair.
