	bool "Build a big kernel"
	help
	  The C6X function call instruction has a limited range of +/- 2MiB.
	  This is sufficient for most kernels, but some kernel configurations
	  with lots of compiled-in functionality may require a larger range
	  for function calls. Use this option to have the compiler generate
	  function calls with 32-bit range. This will make the kernel both
	  larger and slower.

	  If unsure, say N.

	  Say Y if you plan on running a kernel in big-endian mode.
	  Note that your board must be properly built and your board
	  port must properly enable any big-endian related features
	  of your chipset/board/processor.

config FORCE_MAX_ZONEORDER
	int "Maximum zone order"
	default "13"
	help
	  The kernel memory allocator divides physically contiguous memory
	  blocks into "zones", where each zone is a power of two number of
	  pages.  This option selects the largest power of two that the kernel
	  keeps in the memory allocator.  If you need to allocate very large
	  blocks of physically contiguous memory, then you may need to
	  increase this value.

	  This config option is actually maximum order plus one. For example,
	  a value of 11 means that the largest free memory block is 2^10 pages.
