Hello,
I'm wondering how much C preprocessor syntax one can use in DT files.
Suppose I have 2 board DTS (both including common.dtsi)
board_A.dts (1-core), board_B.dts (2-core)
Can I have in common.dtsi something along these lines:
cpus {
enable-method = "foo,bar";
#address-cells = <1>;
#size-cells = <0>;
cpu0: cpu@0 {
compatible = "arm,cortex-a9";
device_type = "cpu";
reg = <0>;
};
#if CORE_COUNT > 1
cpu1: cpu@1 {
compatible = "arm,cortex-a9";
device_type = "cpu";
reg = <1>;
};
#endif
};
board_A.dts would have
#define CORE_COUNT 1
#include "common.dtsi"
board_B.dts would have
#define CORE_COUNT 2
#include "common.dtsi"
Regards.
