57 | config C6X_BIG_KERNEL | |
58 | bool "Build a big kernel" | |
59 | help | |
60 | The C6X function call instruction has a limited range of +/- 2MiB. | |
61 | This is sufficient for most kernels, but some kernel configurations | |
62 | with lots of compiled-in functionality may require a larger range | |
63 | for function calls. Use this option to have the compiler generate | |
64 | function calls with 32-bit range. This will make the kernel both | |
65 | larger and slower. | |
66 | ||
67 | If unsure, say N. | |

83 | On some architectures there is currently no way for the boot loader | |

85 | supply some command-line options at build time by entering them | |
86 | here. | |

97 | bool "Build big-endian kernel" | |
98 | default n | |
99 | help | |
100 | Say Y if you plan on running a kernel in big-endian mode. | |
101 | Note that your board must be properly built and your board | |
102 | port must properly enable any big-endian related features | |
103 | of your chipset/board/processor. | |

105 | config FORCE_MAX_ZONEORDER | |
106 | int "Maximum zone order" | |
107 | default "13" | |
108 | help | |
109 | The kernel memory allocator divides physically contiguous memory | |
110 | blocks into "zones", where each zone is a power of two number of | |
111 | pages. This option selects the largest power of two that the kernel | |
112 | keeps in the memory allocator. If you need to allocate very large | |
113 | blocks of physically contiguous memory, then you may need to | |
114 | increase this value. | |
115 | ||
116 | This config option is actually maximum order plus one. For example, | |
117 | a value of 11 means that the largest free memory block is 2^10 pages. | |
