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

65 | help | |
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 | |
69 | here. | |

80 | bool "Build big-endian kernel" | |
81 | default n | |
82 | help | |
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" | |
90 | default "13" | |
91 | help | |
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 | |
97 | increase this value. | |
98 | ||
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. | |
