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

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

| config CPU_BIG_ENDIAN |
| bool "Build big-endian kernel" |
| default n |
| help |
| Say Y if you plan on running a kernel in big-endian mode. |
| Note that your board must be properly built and your board |
| port must properly enable any big-endian related features |
| of your chipset/board/processor. |
| |
| config FORCE_MAX_ZONEORDER |
| int "Maximum zone order" |
| default "13" |
| help |
| The kernel memory allocator divides physically contiguous memory |
| blocks into "zones", where each zone is a power of two number of |
| pages. This option selects the largest power of two that the kernel |
| keeps in the memory allocator. If you need to allocate very large |
| blocks of physically contiguous memory, then you may need to |
| increase this value. |
| |
| This config option is actually maximum order plus one. For example, |
| a value of 11 means that the largest free memory block is 2^10 pages. |
