Use this option to have the compiler generate 51 function calls with 32-bit range. This will make the kernel both 52 larger and slower. 53 54 If unsure, say N. 55 56# Use the generic interrupt handling code in kernel/irq/ 57 58config CMDLINE_BOOL 59 bool "Default bootloader kernel arguments" 60 61config CMDLINE 62 string "Kernel command line" 63 depends on CMDLINE_BOOL 64 default "console=ttyS0,57600" 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. 70 71config CMDLINE_FORCE 72 bool "Force default kernel command string" 73 depends on CMDLINE_BOOL 74 default n 75 help 76 Set this to have arguments from the default kernel command string 77 override those passed by the boot loader. 78 79config CPU_BIG_ENDIAN 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. 87 88config 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. 101 102menu "Processor type and features" 103 104source "arch/c6x/platforms/Kconfig" 105 106config KERNEL_RAM_BASE_ADDRESS 107 hex "Virtual address of memory base" 108 default 0xe0000000 if SOC_TMS320C6455 109 default 0xe0000000 if SOC_TMS320C6457 110 default 0xe0000000 if SOC_TMS320C6472 111 default 0x80000000 112 113source "kernel/Kconfig.hz" 114 115endmenu 116
