config SH_UNKNOWN
	bool "BareCPU"
	help
	  "Bare CPU" aka "unknown" means an SH-based system which is not one
	  of the specific ones mentioned above, which means you need to enter
	  all sorts of stuff like CONFIG_MEMORY_START because the config
	  system doesn't already know what it is.  You get a machine vector
	  without any platform-specific code in it, so things like the RTC may
	  not work.

	  This option is for the early stages of porting to a new machine.

	  Computers built with Hitachi SuperH processors always
	  map the ROM starting at address zero.  But the processor
	  does not specify the range that RAM takes.

	  The physical memory (RAM) start address will be automatically
	  set to 08000000, unless you selected one of the following
	  processor types: SolutionEngine, Overdrive, HP620, HP680, HP690,
	  in which case the start address will be set to 0c000000.

	  Tweak this only when porting to a new machine which is not already
