This should conflict with the memory defined in this file:

        memory@80000000 {
                device_type = "memory";
                /* We expect the bootloader to fill in the size */
                reg = <0 0x80000000 0 0>;
        };

I think this should be updated?

Vinod,

I prefer we leave ^^ node untouched.
For platforms using hyp_mem, the
regions defined in the memory map
are valid and for the other platforms
not using hyp_mem we would just delete
them in the board files anyway.
