If I did it with adding unit address
- memory {
+ memory at 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 at 80000000 whose blob disassembly detail is
as the following.
memory {
device_type = "memory";
reg = <0x0 0x0 0x0 0x0>;
};
memory at 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 ?
