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

59 bool "Default bootloader kernel arguments"
62 string "Kernel command line"
63 depends on CMDLINE_BOOL
64 default "console=ttyS0,57600"
66 On some architectures there is currently no way for the boot loader
67 to pass arguments to the kernel. For these architectures, you should
68 supply some command-line options at build time by entering them
72 bool "Force default kernel command string"
73 depends on CMDLINE_BOOL
76 Set this to have arguments from the default kernel command string
77 override those passed by the boot loader.
80 bool "Build big-endian kernel"
83 Say Y if you plan on running a kernel in big-endian mode.
84 Note that your board must be properly built and your board
85 port must properly enable any big-endian related features
86 of your chipset/board/processor.
88 config FORCE_MAX_ZONEORDER
89 int "Maximum zone order"
92 The kernel memory allocator divides physically contiguous memory
93 blocks into "zones", where each zone is a power of two number of
94 pages. This option selects the largest power of two that the kernel
95 keeps in the memory allocator. If you need to allocate very large
96 blocks of physically contiguous memory, then you may need to
99 This config option is actually maximum order plus one. For example,
100 a value of 11 means that the largest free memory block is 2^10 pages.
