Currently, the do_compile log is cluttered with dtc warnings that should only be printed when compiling with W="123": ... /soc: node has a reg or ranges property, but no unit name /soc/gpu: missing or empty reg/ranges property /soc/firmware/gpio: missing or empty reg/ranges property ... This happens because we pass dtc flags via KERNEL_EXTRA_ARGS directly on the make command line, preventing scripts/Makefile.lib logic from appending flags that silence dtc warnings (all assignments done from within a makefile, to a variable specified on the command line, are ignored). oe-core commit [1] introduced the dedicated KERNEL_DTC_FLAGS variable to pass dtc flags via the environment. Use this variable to get rid of the do_compile log noise. The md5sums of the generated dtbs for raspberrypi3-64 and raspberrypi4-64 do not change with this patch applied.
