	bool "Symmetric Multi-Processing"
	help
	  This enables support for systems with more than one CPU. If
	  you say N here, U-Boot will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor
	  machine. If you say Y here, U-Boot will run on many, but not
	  all, single processor machines.

	default 8
	help
	  On multiprocessor machines, U-Boot sets up a stack for each CPU.
	  Stack memory is pre-allocated. U-Boot must therefore know the
	  maximum number of CPUs that may be present.
