43config C6X_BIG_KERNEL
44 bool "Build a big kernel"
45 help
46 The C6X function call instruction has a limited range of +/- 2MiB.
47 This is sufficient for most kernels, but some kernel configurations
48 with lots of compiled-in functionality may require a larger range
49 for function calls. Use this option to have the compiler generate
50 function calls with 32-bit range. This will make the kernel both
51 larger and slower.
52
53 If unsure, say N.

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

75 Set this to have arguments from the default kernel command string

78config CPU_BIG_ENDIAN
79 bool "Build big-endian kernel"
80 default n
81 help
82 Say Y if you plan on running a kernel in big-endian mode.
83 Note that your board must be properly built and your board
84 port must properly enable any big-endian related features
85 of your chipset/board/processor.

87config FORCE_MAX_ZONEORDER
88 int "Maximum zone order"
89 default "13"
90 help
91 The kernel memory allocator divides physically contiguous memory
92 blocks into "zones", where each zone is a power of two number of
93 pages. This option selects the largest power of two that the kernel
94 keeps in the memory allocator. If you need to allocate very large
95 blocks of physically contiguous memory, then you may need to
96 increase this value.
97
98 This config option is actually maximum order plus one. For example,
99 a value of 11 means that the largest free memory block is 2^10 pages.
