41config C6X_BIG_KERNEL
42	bool "Build a big kernel"
43	help
44	  The C6X function call instruction has a limited range of +/- 2MiB.
45	  This is sufficient for most kernels, but some kernel configurations
46	  with lots of compiled-in functionality may require a larger range
47	  for function calls. Use this option to have the compiler generate
48	  function calls with 32-bit range. This will make the kernel both
49	  larger and slower.
50
51	  If unsure, say N.

66	help
67	  On some architectures there is currently no way for the boot loader
68	  to pass arguments to the kernel. For these architectures, you should
69	  supply some command-line options at build time by entering them
70	  here.

77	  Set this to have arguments from the default kernel command string
78	  override those passed by the boot loader.

80config CPU_BIG_ENDIAN
81	bool "Build big-endian kernel"
82	default n
83	help
84	  Say Y if you plan on running a kernel in big-endian mode.
85	  Note that your board must be properly built and your board
86	  port must properly enable any big-endian related features
87	  of your chipset/board/processor.
88
89config FORCE_MAX_ZONEORDER
90	int "Maximum zone order"
91	default "13"
92	help
93	  The kernel memory allocator divides physically contiguous memory
94	  blocks into "zones", where each zone is a power of two number of
95	  pages.  This option selects the largest power of two that the kernel
96	  keeps in the memory allocator.  If you need to allocate very large
97	  blocks of physically contiguous memory, then you may need to
98	  increase this value.
99
100	  This config option is actually maximum order plus one. For example,
101	  a value of 11 means that the largest free memory block is 2^10 pages.
