The opos6uldev_defconfig has "CONFIG_POWER_DOMAIN=y", so when building SPL, this macro is still effective. Opos6uldev compiles driver/core/device.c which includes power-domain.h in my later patch. Because driver/power/domain is not built for SPL, so build failure for SPL. The simple method for now is to undef CONFIG_POWER_DOMAIN for SPL build. If use CONFIG_IS_ENABLED, the undef CONFIG_POWER_DOMAIN will not be detected in Kconfig. Simply introduce SPL_POWER_DOMAIN could not fix this issue. Need to let SPL choose CONFIG_SPL_POWER_DOMAIN, but not CONFIG_POWER_DOMAIN, I do not have a clear idea on how.
