	  Enable this to get low level debug messages during barebox
	  initialization. This is helpful if you are debugging code that
	  executes before the console is initialized.

	  This requires SoC specific support. Most SoCs require the
	  debug UART to be initialized by a debugger or first stage
	  bootloader.

	  Note that selecting this option will limit barebox to a single
	  UART definition, as specified below under "low-level debugging
	  port". Attempting to boot the resulting image on a different
	  platform *will not work*, so this option should not be enabled
	  for builds that are intended to be portable.
