It is global include header file, so I though it would be better to not export lot of other macros which are relevant only for CONFIG_SYS_REF_CLK But if you want to see names, I can change it e.g. to: +#elif defined(CONFIG_ARMADA_3700) +/* SAR values for Armada 3700 */ +#define MVEBU_TEST_PIN_LATCH_N MVEBU_REGISTER(0x13808) +#define MVEBU_XTAL_MODE_MASK BIT(9) +#define CONFIG_SYS_REF_CLK ((readl(MVEBU_TEST_PIN_LATCH_N) & MVEBU_XTAL_MODE_MASK) ? \ + 40000000 : 25000000)
