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

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

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

77config CPU_BIG_ENDIAN
78 bool "Build big-endian kernel"
79 default n
80 help
81 Say Y if you plan on running a kernel in big-endian mode.
82 Note that your board must be properly built and your board
83 port must properly enable any big-endian related features
84 of your chipset/board/processor.

86config FORCE_MAX_ZONEORDER
87 int "Maximum zone order"
88 default "13"
89 help
90 The kernel memory allocator divides physically contiguous memory
91 blocks into "zones", where each zone is a power of two number of
92 pages. This option selects the largest power of two that the kernel
93 keeps in the memory allocator. If you need to allocate very large
94 blocks of physically contiguous memory, then you may need to
95 increase this value.
96
97 This config option is actually maximum order plus one. For example,
98 a value of 11 means that the largest free memory block is 2^10 pages.
