Thanks. I see the following in v1.9.6 of the BSP[1]. Is it
the same as the document you referred to above?


		partition@0 {
			label = "loader";
			reg = <0x00000000 0x00080000>;
			read-only;
		};
		partition@40000 {
			label = "user";
			reg = <0x00080000 0x00580000>;
			read-only;
		};
		partition@440000 {
			label = "flash";
			reg = <0x00600000 0x03a00000>;
		};
