If I did it with adding unit address
- memory { + memory@80000000 { device_type = "memory"; reg = <0 0x80000000 0 0x80000000>; };
bad dtc blob is being generated and contains two memory nodes, one is memory and the other is memory@80000000 whose blob disassembly detail is as the following.
memory { device_type = "memory"; reg = <0x0 0x0 0x0 0x0>; };
memory@80000000 { device_type = "memory"; reg = <0x0 0x80000000 0x0 0x80000000>; };
and bad memory node with size 0 would cause the boot fails.
is it a dtc compiler problem ?
