Currently it is not possible to completely silent the debug console in i.e. PX30, what might be required in some embedded devices Disabling DEBUG_UART results in errors, due to missing symbols. In particular, rockchip sdram driver performs calls to debug_uart functions (i.e. printascii), defined directly in serial driver. This patch series fixes the dependencies in Kconfig and provides dummy implementation of debug_uart functions that are linked in case serial driver is not used.
